Biography
May 16, 2024
What do you like about your job and/or about working at the Lab?
I'm involved in a few projects that bring together small teams of people with different backgrounds. It's awesome to work on teams where I bring subject matter expertise in one area—quantum computing or quantum sensing, usually—and am interfacing with others who bring really deep knowledge in other areas, like making really low noise microwave signals or simulating how light interacts with plasmas.
What is your educational/career background?
I joined LLNL in 2020. Prior to LLNL, I was a senior physicist at the startup quantum computing company IonQ, which spun out of the group I did my postdoctoral work with at the University of Maryland. I received my Ph.D. from MIT in 2016, my M.Phil. from the University of Cambridge in 2010 and my B.S. in Physics and B.A. in Mathematics (with a minor in music) from the University of Rochester in 2019.
What inspired you to go into science/your field of work?
My parents are both engineers and encouraged me to explore science and engineering. When I kept asking how things worked, they encouraged me to study physics. While the questions that keep me busy most days straddle the boundary between physics and engineering, I stayed in physics because I love and am challenged by the research environment of tabletop physics. I find it immensely satisfying to have the command of an entire lab space and understand how each sub system impacts other ones, from the seemingly mundane water cooling method to lasers and RF test equipment to the physics questions I'm ultimately trying to answer or elucidate.

Biography
March 29, 2024
What do you like about working at the Lab?
My favorite thing about working at LLNL is getting to work with really smart and passionate people and getting to discuss interesting and challenging problems with them. Beyond that, having access to some of the best scientific resources in the world (e.g., NIF and HPC), getting to constantly learn and participate in cutting-edge science, and being able to directly contribute to national security and real-world applications is hard to beat!
What do your day-to-day work activities include?
My job requires a variety of different tasks, therefore, my day-to-day work varies. This might include several meetings trying to coordinate and execute the large-scale/team science that we carry out at LLNL, reading material and/or asking our SMEs about whatever topic/question I'm trying to track down at the moment, or carrying out simulations and/or developing analyses for my different projects.
What is one project you’re really proud to have worked on?
I'm still relatively new at the Lab so I don't have a large list of projects that I "have" worked on so much as I have several projects that I am excited to currently "be" working on. At the top of the list is my neutron survivability work and the PROACTIVE arms control venture that has just begun.
What is your educational or career background?
I started out at a small liberal arts college with a double major in physics and business administration and then pivoted (somewhat) to getting a PhD in nuclear engineering with a focus on radiation detection for nonproliferation applications. From there I spent a year doing the NNSA Graduate Fellowship in NNSA's Office of Defense Nuclear Nonproliferation Research and Development before starting at LLNL in August 2021.
What inspired you to go into science?
My interest in science really bloomed in high school thanks to my AP chemistry and physics courses. I love learning in general, but in particular trying to understand our universe/nature is not only fascinating but I think one of the most inspiring things about humanity. I knew I wanted to study chemistry or physics, and the chemistry course was full my freshman year so voila, I became a physics major! When considering grad school, I was really interested in particle physics, but I wasn't sure I wanted to commit to six more years of school and also wanted something more applied to facilitate staying in research/science outside of academia. I then had a dream about becoming a nuclear engineer, woke up and looked into it, and then proceeded to stumble into the field of radiation detection for nonproliferation, which more or less landed me where I am now!
What advice would you give to a new employee at the Lab?
Take advantage of opportunities to learn about all the awesome work going on at the Lab and its history, people here like talking about their work and helping others so don't be afraid to reach out and ask questions/for help. Lastly, appreciate how unique and rewarding working at LLNL is.
What do you do in your free time?
In my free time I enjoy exercising (weightlifting, basketball, running), reading (trying to find the balance between reading to learn vs reading for fun), am currently learning Russian, and have just started using my scuba diving certification!
March 15, 2024
What do you like about working at the Lab?
I love the freedom and creativity that I have here. I feel like any time I get a project, I am able to be creative with it and really just run with my ideas. I consider myself to be a "translator of the sciences," and I love breaking tough science topics down into easier to understand articles that even non-scientific folks, like myself, can understand.
What do your day-to-day work activities include?
I am usually bouncing between several projects—working on an ongoing article, interviewing people across PLS, putting together a presentation, updating website content, working with other creative staff members like our graphic designers or videographers, writing the weekly PLS Notable Newsletter, etc.
What is one project you’re really proud to have worked on?
I work on a lot of projects, but writing is my favorite thing to do, so I would have to say my favorite project is the article I wrote on a ROTC summer intern for the Energetic Materials Center.
What is your educational or career background?
I have a bachelor's in communications, a minor in art history, and am working on finishing my master's in English.
What inspired you to go into your field of work?
I have always had a knack for writing essays but never really imagined writing about science as a career until I came to the Lab. Now, there is no place I'd rather be.
What advice would you give to a new employee at the Lab?
Don't pretend like you know what something (like an acronym) means!! If you have a question, ask it! It is always better to ask in the moment then to later regret not having asked.
What do you do in your free time?
I love going to San Francisco, visiting art museums, going on runs/to the gym, and cuddling with my cat Tommy T. I'm a member of the Lawrence Livermore Laboratory Women's Association (LLLWA) employee resource group.

December 12, 2023
What do you like about working at the Lab?
I really enjoy the teams of people I work with and our project scopes. It's a really creative and innovative environment where we can often utilize really cool and cutting edge scientific approaches and techniques.
What do your day-to-day work activities include?
About half of the day, I spend doing hands-on laboratory work, mostly molecular and cellular biology. This includes passaging tissue culture lines or doing viral challenges, setting up and performing various in vitro assays, cloning new constructs, or generating new cell lines. The other half of my day is spent in meetings, analyzing data, writing reports, making presentations, and collaborating with others.
What is one project you’re really proud to have worked on?
Without a doubt, the COVID-related projects. I've been a team member on various SARS-CoV-2 countermeasure projects, ranging from small-molecule inhibitors of viral proteins up to computationally designed neutralizing antibodies. These projects have been both internally and externally sponsored, and have a wide-ranging team encompassing all different scientific backgrounds. It's been a great experience to work so collaboratively with so many people on such an important focus point!
What is your educational or career background?
I have a bachelor's degree in Biotechnology from UC Davis, and went to work in biotech at a genomics startup. I left to pursue my PhD in Microbiology, Immunology, & Molecular Genetics from UCLA. I did a postdoc in the Systems Biology group at Sandia National Laboratories prior to joining LLNL.
What inspired you to go into your field of work?
I've always been drawn to the sciences. I used to joke that "Jurassic Park" is what took me to Biotechnology originally. I wanted to be the scientist who hatched and played with the baby dinos (but got off the island safely before the storm, of course). Once in college, I had the opportunity to take so many different lecture and laboratory courses, and really got interested in molecular mechanisms, and over time I really felt drawn towards medical microbiology. Infectious diseases, how they're caused, how to combat them. I now find myself working at the intersection of host-pathogen interactions, and how to apply new cutting-edge techniques (like CRISPR) in pursuit of countermeasures and therapeutics. I find it to be really rewarding and important work for scientific advancement, as well as public health and biosecurity.
What advice would you give to a new employee at the Lab?
I'd recommend trying to meet many people, and keep open to new possibilities. I started during the COVID shutdown, and it took me a while to meet lots of people, but I'm constantly surprised and interested by all the cool science and work being done all around, but also made so many friends that make this a great place to be.
What are your hobbies/what do you do in your free time?
I really enjoy spending family time together with my wife and young daughter. We enjoy playing outside, going on hikes, and love exploring on day trips (including zoos, aquariums, and museums), and hopefully traveling more once COVID is less of a concern. Otherwise, I love curling up around a good book, especially space Sci-Fi.

Biography
February 17, 2023
What do you like about working at the Lab?
At the Laboratory, we have the opportunity to tackle some of the most challenging scientific problems of our time. This is a curse (it's not easy) and a blessing (it matters). In my case, I work on understanding the fundamental mechanisms of nuclear fission. Fission, and nuclear reactions in general, are qualitatively well understood, but developing sufficiently precise theoretical models for relevant applications at the Lab is extraordinarily difficult. It requires sustained investments, sometimes over decades, which would be difficult to secure in an academic environment. This long-term perspective is one of the things I like the most about the Laboratory.
What do your day-to-day work activities include?
I wish I could say that I sit at my desk and ponder about atomic nuclei. Sadly, this is not the case, as there are many other pressing items that require my attention. Instead, I write a lot of emails throughout the day and attend (too many) meetings. Some of meetings are on mundane administrative topics like office space, others are more stimulating and involve brainstorming to solve a problem. Other times, I am working to improve and debug my programs, which does take a good amount of my time. Like every other scientist, an article or proposal will come my way that requires my review. Depending on the time of the year, I may also have to prepare a rather large number of reports, proposals, or slides for various people.
What is one project you’re really proud to have worked on?
There is no single project that I am really proud to have worked on. In fact, it is quite the opposite: what I am most proud of is that I have been able to (so far) work on multiple projects beyond my comfort zone. I have been working on modernizing our computer codes to adapt them on the advanced architectures pioneered at the Laboratory. Additionally, I have been exploring how machine learning techniques can be applied to solve some of the problems we have in nuclear theory. Most recently, I am interacting with experimentalists a lot more to learn how to produce quality nuclear data for applications. This variety keeps life interesting.
What is your educational or career background?
I am a standard product of the French educational system—I did the first two years of my undergraduate studies in what are called 'Classes Preparatoires aux Grandes Ecoles' in Bordeaux. I obtained a bachelor's in physics, master's in nuclear physics, and a physics engineering degree at the University of Strasbourg. After receiving a PhD in theoretical nuclear physics from the same university, I did a string of postdocs at the University of Surrey (UK), Universidad Autonoma de Madrid (Spain), and University of Tennessee. I then joined the Lab in 2010 as a staff scientist in the nuclear data and theory group.
What inspired you to go into science/your field of work?
As a child, most of us never stopped asking our parents and teachers (or any grown-up around us) questions about why things are the way they are. I guess I was never satisfied with whatever answer I was given, so I have continued to ask myself questions ever since. Science can be very frustrating, but the few answers that sometimes trickle out of my research bring a very soothing sense of order into the chaos that is the universe. This strange reason of why I got into science in the first place may also explain why I specialized in theoretical physics.
What advice would you give to a new employee at the Lab?
I arrived at the Lab already as a seasoned physicist with a good network of collaborators, some relatively clear ideas about my research, and a decent amount of experience in the research community. This probably made the transition much easier than if I had joined fresh out of grad school. My main focus in the first few years was to understand the sometimes arcane system of funding, learn at least a subset of the zillions of acronyms used here, and generally speaking—adapt myself to an organization that is different from a university or a basic science institute. As a Laboratory employee, we are part of a team, and the first thing to do is learn about the team.
What are your hobbies/what do you do in your free time?
I try to convince my body that it can still sustain the same amount of sport as when I was a teenager. It usually fails, so I also spend a lot of time reading books.

Biography
August 19, 2022
What do you like about working at the Lab?
One of the primary things I love about working at LLNL is the quality and diversity of my colleagues here. The Lab has an amazing depth of knowledge and a variety of disciplines beyond my current focus on particle physics. Here I can balance my interests in fundamental science with applied research that can materially support the nation.
What do your day-to-day work activities include?
I lead an experiment that looks for extremely faint microwave signals from primordial dark matter, in a similar fashion of how one would look for a radio station with an AM radio. This includes designing, constructing, and installing tunable microwave resonators to enhance the signal and suppress backgrounds, allowing us to search quickly through a large set of frequencies (equivalent to the mass of the particle). In addition, I’m fortunate to be the point-of-contact for the Department of Energy (DOE) High Energy Physics (HEP) program which includes telescope searches for dark energy, neutrino experiments, detector R&D, and theory and laser acceleration studies.
What is one project you’re really proud to have worked on?
I’m extremely proud to be working on the Axion Dark Matter Experiment (ADMX). ADMX started at LLNL in the 1990s, and after a series of upgrades, it is now one of the DOE HEP Cosmic Frontier “Generation 2” direct dark matter search projects and the DOE’s flagship US search for axion dark matter. This is currently the most sensitive experiment in the world for axions in the gigagertz (GHz) frequency range and we continue to take data in at an increasing speed (which means detection could occur at any time now).
What is your educational or career background?
I got my bachelor’s in physics from Harvey Mudd College and my PhD in physics from the Massachusetts Institute of Technology. In between undergrad and grad school I spent a summer as a research scientist at the Jet Propulsion Laboratory. I came to LLNL 15 years ago, directly after graduate school, as a postdoctoral researcher and transitioned to a staff scientist a few years later.
What inspired you to go into science/your field of work?
I remember reading Stephen Hawking’s “A Brief History of Time” in middle school and it completely blew my mind. I couldn’t believe the relation between time and space and how you can calculate the evaporation of a black hole from quantum mechanics. The fact that beautiful mathematics can describe nature but also that deep mysteries still exist and require exploration has always driven my desire to explore our natural world at the most fundamental level.
What advice would you give to a new employee at the Lab?
My advice would be to explore this exceptional place and to carve out the time in your busy schedule to attend presentations and visit with groups outside of your current work area. Be proactive and curious and you’ll have a very rich experience here.
What are your hobbies/what do you do in your free time?
I like to go running and I’m a big movie nerd.

A lot of my day-to-day activities include making sure that our group is succeeding in our field and laboratory work. I also spend a lot of my time interpreting and discussing data, writing scientific papers, and developing new research proposal ideas.
What is one project you’re really proud to have worked on?
It’s so hard to choose just one—I have worked with many great people on a variety of interesting projects. I’m really proud of the Spruce and Peatland Responses Under Climatic and Environmental Changing Environments (SPRUCE) experiment. SPRUCE is a US Department of Energy project where a large group of scientists and researchers, myself included, are learning about the impacts of climate change on a forested peatland in Minnesota.
What is your educational or career background?
After high school, I have a BS in environmental science from DePaul University, MS at the State University of New York’s College of Environmental Science and Forestry (yep, it’s a mouthful!), and finally a PhD in forest engineering with a minor in soil science from Oregon State University. I started my postdoctoral research position a few weeks after finishing school, and I have been at the Lab for 14 years.
What inspired you to go into science?
I was always curious, especially about nature and the relationship between plants and animals (including humans). When I was young, I also wondered about Earth’s place in the universe and was interested in space, stars, and other planets. I went to space camp when I was in 8th grade and discovered that I really wanted to learn about Earth—there are so many interesting things to learn about right here! At that time, people were worried about protecting wetlands and tropical forests. Learning about those ecosystems and helping to protect them felt really important to me. I also cared a lot about environmental justice and the impacts of climate change on ecosystems and human communities. Working at the Lab and researching the interactions between climate and environmental systems has been a great fit for me.

What do you like about working at the Lab?
LLNL presents enormous opportunities for multi-disciplinary projects that simply couldn't happen in a university setting, at least not easily. While at LLNL, through LDRD, I've had the chance to work closely with the world's best optical, electrical, and computer engineers in multiple directorates.
What is one project you’re really proud to have worked on?
I'm very excited to have led the development of the LLAMAS adaptive optics system, a state-of-the-art prototype that pushes the limits of adaptive optics compensation in challenging turbulent environments. LLAMAS demonstrates advanced technologies like low-latency computing and control algorithms that will be needed for future extremely large telescopes in astronomy and in other domains.
What is your educational or career background?
I obtained my PhD in astronomy and astrophysics at UC Santa Cruz, working within the Center for Adaptive Optics. LLNL was a major player in the Center. Following that, I took a Hubble Fellowship at the University of Arizona to study gravitational lensing in galaxy clusters. And I've been at the Lab for ten years.
What inspired you to go into science?
Many of us have looked through small telescopes and then were delighted to see the rings of Saturn or the moons of Jupiter up close. But when I first did so, my excitement quickly became disappointment as atmospheric turbulence blurred the image and prevented me from seeing more details. At an REU at the National Solar Observatory, I discovered these adaptive optics systems that can "fix" the turbulence and bring telescope images into sharp focus. I've been hooked ever since.
What advice would you give to a new employee at the Lab?
Use your postdoctoral years to build relationships beyond your local research group. Some of these can eventually result in new opportunities and open doors. Most of the people reviewing your work and proposals will not be technical experts in your field, so it helps to have a wide network throughout the Lab.

August 5, 2021
What do you like about working at the Lab?
What I like about my job is learning new science that was previously unknown. The moment of discovery is incredibly fulfilling (especially when it is something we never anticipated based on calculations or simulations). The potential for discovering new science is there because much of the research we perform is forefront science. I love that the Lab provides not only an amazing set of tools to perform frontier experiments, but also an ability to build diagnostics that allow us to perform experiments that would be extremely difficult to perform without LLNL resources. Additionally, the ability to walk into the office of world-class experts to get advice on almost any topic makes the Lab an incredible place for all scientific specialties.
What do your day-to-day work activities include?
My work varies from day to day. Some days I perform calculations to model spectral output from current experiments or help design new experiments. Other days, I test or prepare equipment for upcoming experiments in the lab. Then other days, I discuss ideas for new experiments with colleagues or work with a graduate student or young scientist in an attempt to pass on as much of what I've learned as possible.
What is one project you’re really proud to have worked on?
I'm very proud to have worked on the short pulse laser heated buried layer opacity project. It is a platform that has taken many years to develop and ultimately required developing the world’s first sub-picosecond x-ray diagnostic to get data. The platform is unique in its ability to create relatively high-temperature, high-density plasma with minimal spatial gradients. To this end, the platform has carved out a unique density-temperature phase space to study fundamental plasma physics phenomena. Because I was at LLNL while early high-intensity, short-pulse lasers were being developed, I was fortunate enough to be amongst a handful of individuals around the world to work on the concept.
What is your educational or career background?
I earned a BSE in nuclear engineering and an MS and PhD in plasma physics from the University of Michigan. I’ve worked at the Lab for 34 years.

What advice would you give to a new employee at the Lab?
For young scientists, build a portfolio of Laboratory Directed Research and Development (LDRD). Try to gauge the topics that are in vogue by attending meetings and discussing ideas with the programs. If you submit an LDRD one year and it's not funded, write a new LDRD the following year and submit that, but keep the previous year's LDRD at hand. And if (eventually) topics you've based your LDRDs on become popular, resubmit your idea. Building a portfolio of written LDRDs helps new scientist understand the LDRD process and simplifies the proposal submission procedure.
What do you do in your free time?
I enjoy science fiction, sports cars, independent films, trying to learn about basic physical phenomena (inertia is a current interest), and sports (college football, basketball, and women's soccer). I’m also a member of the African American Body of Laboratory Employees.

May 28, 2021
What do you like about working at the Lab?
I like the diversity of projects I am exposed to and involved in. The Lab is a big place, and as I like to tell people I meet at recruiting events, regardless of your field of expertise, the Lab has a directorate/division/group for you! The breadth of work done at the Lab and the contributions that are made to so many different fields is impressive. I also genuinely like our moto—science and technology on a mission. I think it is rewarding to assist on projects and programs that are relevant to us all.
What do your day-to-day work activities include?
I spend most of my day in front of a computer running numerical simulations, debugging codes, writing scripts and the like, and reading articles. The rest of the time, I attend meetings to discuss given projects with colleagues, or seminars. These days, as I am PI on a project, I also have to dedicate a portion of the day to managing and reporting.
What is one project you’re really proud to have worked on?
It’s actually a project that I am the PI on and that just started. Our team is assessing the practical use of seismoelectric effects for geothermal resources monitoring in an integrating approach using numerical modeling, laboratory experiments, and ultimately field experiments. It’s an international team with colleagues in France and Norway. I am particularly excited because I thought about exploiting and modeling seismoelectric effects, which are subsurface pore scale phenomena related to seismic-to-electric conversion, as a natural next step following a project I worked on as a postdoc just before joining the Lab ten years ago. Fast forward six years, and I was awarded a LDRD Lab wide, an internal funding program, to numerically model these phenomena. Building on that work, I am now collaborating with a multidisciplinary team to move what is still a novel technique to the next level of practical use. It doesn’t get more exciting!
What is your educational or career background?
My background isn’t linear, as I am originally a chemical engineer who went on to pursue a PhD in geophysics, with a thesis on geodynamical modeling of Earth mantle convection and its interaction with the lithosphere, in France. Over the course of my subsequent postdocs and research associate position, in Canada and the US, I changed the scale of my focus from modeling Earth mantle convection to modeling tectonic deformation at the crustal scale, and finally, to simulating seismic wave propagation to probe the subsurface. I joined the Lab ten years ago and focus my work on using both seismic and electromagnetic modeling for geophysical imaging and monitoring.
What inspired you to go into science?
I always liked STEM in general and how science helps us understand the world around us and how things work. Paradoxically, I like the level of certainty associated with science, but also the questioning and unknown that is part of a researcher’s life. It’s also this balance between having a specialized knowledge and keeping a beginner’s mindset to solve problems.
What advice would you give to a new employee at the Lab?
Be curious. The Lab is a great place to be exposed to a wide range of disciplines and programs. My experience is that all levels, from colleagues, supervisors, group leaders, and up, are eager to help and assist, so don’t hesitate to show up, speak up, and reach out.
What do you do in your free time?
I like reading, watching movies (yes, I am a Marvel person), and enjoying the many diverse and excellent cuisines in the Bay Area. My wife is a theater nerd, so I also get dragged to plays and musicals…a lot. I am also a member of the African American Body of Laboratory Employees and on the leadership team of Livermore Pride.

Biography
May 28, 2021
What do you like about working at the Lab?
Working at the Lab is almost never boring. Every day comes with exciting new challenges to solve, fresh information to explore, and interesting new people to interact with–often on something you never dreamed you'd be thinking about! I'm in high-energy-density plasma physics (or, "What happens to stuff when it gets REALLY hot?"), which contributes to the development of fusion (clean future energy), understanding stars (basic science), and the stockpile stewardship mission (defense & national service)—that's a fun combination!
What do your day-to-day work activities include?
Email and meetings! I attend meetings about planning and executing large laser experiments, analyze data, and discuss the results to better understand the properties of hot, dense matter. My work involves lots of interdisciplinary teamwork and creative problem solving as well as mentoring and supporting younger staff working on related experiments. I also still manage to do real hands-on work on a NIF diagnostic for our experiment.
What is one project you’re really proud to have worked on?
There are a lot of great projects, but the high point so far has been working on the "Opacity-on-NIF" campaign, a series of experiments that our national team built from scratch to understand how X-rays get absorbed as they pass through a sample of hot, dense plasma that we create. Creating the sample is a combination of baking and photography: the NIF beams heat up a "laser oven" (called a hohlraum), the sample inside the oven gets hot and expands a bit, and then we use more NIF beams to make an x-ray flashbulb and shine the light through the sample. The pride comes after wrestling with many challenges, when the measurements finally start to work and make sense, and we begin seeing things that no one's ever looked at before.
What is your educational or career background?
I received a bachelor's in physics and a PhD in astrophysical sciences. After completing a postdoc fellowship, I became an LLNL staff physicist and currently serve as a senior scientist. I’ve been at the Lab for 21 years.
What inspired you to go into science?
I'm an "accidental physicist." I had no idea what to major in when I got to college, so I started with math and physics since they kept all my options open if I changed my mind. As I explored, I found that I liked math, physics, philosophy, and computer science, but I got along best with the physics classes and students, so it stuck!
What advice would you give to a new employee at the Lab?
The Lab is full of opportunities for those who keep building their skills and contributing wherever they can. And it pays to treat everyone well—you never know who will be on your next team.
What do you do in your free time?
Free time? Working parents don’t get much free time, but I enjoy helping my kids with school, activities, and sports. I enjoy playing tennis and COVID encouraged me to take more time for personal fitness, so I joined the LLESA tennis group. My other hobbies are investing, games, hiking, the occasional movie, and reading (particularly sci-fi, fantasy adventures, and history).

Biography
November 17, 2020
What do you like about working at the Lab?
There is so much opportunity in the Lab to pursue new research directions. I love that my work and research has evolved so much in only two years, and that I’ve been able to work on so many different projects. It is also amazing to be surrounded by people who are world-wide experts in their field and to have so many resources onsite that allow us to do cutting-edge work. It’s really incredible to be able to work on teams with these experts and to learn from them.
What do your day-to-day work activities include?
My days vary greatly week to week. Some weeks I’m at my desk working up data, attending meetings, or coordinating with collaborators on how to move forward the work that needs to be done. Other weeks, I find myself in lab most of the time, setting up and performing experiments or characterizing the materials after the experiment has finished. Sometimes, I’ll be traveling for an experiment at another national lab or at a research conference. I like having a mix of hands-on research responsibilities in the lab and more computer-based project management responsibilities.
What do you do in your free time?
I enjoy running, downhill skiing, hiking, cooking, and traveling. Recently, I’ve been taking on DIY projects, like trying to use reclaimed wood to make something useful. I spend a lot of time in the garden trying to grow fruits and vegetables. I’m a member of the Organic Gardening Networking Group at the Lab.
What is your educational or career background?
I received my BS in materials chemistry from University of California, Los Angeles. While I was there, I worked with the thermoelectric materials group at NASA’s Jet Propulsion Laboratory. That’s where I really fell in love with research, and it’s what seeded my desire to return to a national lab. I went on to do my PhD at Northwestern University, where I tried to make new materials at high pressure conditions. This work eventually led me to seek a postdoctoral position here!
What advice would you give to a new employee at the Lab?
This is a tough one right now. I’d typically say try to meet new people by going to events or just showing up to the cafeteria and asking to sit at a random table. Or email someone you’ve met once to see if they want to get lunch or a coffee. Right now, when much of the Lab is working from home and managing other responsibilities that have come with this new normal, this is more difficult, and a WebEx lunch may not even be possible for some. I guess my advice right now would be to stay strong, reach out to those on your team and in your group to stay connected, and once things go back to normal, let’s get lunch!

November 2, 2020
What do you like about working at the Lab?
I feel a great pride and drive to work on problems that are important to our national security. And I enjoy the people I work with tremendously. I think those two things make working at LLNL great. I also enjoy working on real problems that challenge me scientifically and allow me to foster new solutions with technical rigor.
What do your day-to-day work activities include?
I’m the director of materials compatibility, and I lead a team of scientists and engineers in assessing the long-term stability and chemical compatibility of material assemblies. My kids say, “you sure do spend a lot of time in meetings!” and they’re right because I spent a lot of my time talking to the technical experts in materials and compatibility to answer technical questions from our weapons programs. It is a desk job where I talk to people in meetings or on the phone, email a lot, prepare presentations, manage budgets, and schedule activities. Sometimes I travel to conferences or meetings at other national labs. Underneath all that is the bigger goal of developing new capabilities and working to solve challenging materials compatibility problems.
What is one project you’re really proud to have worked on?
My proudest accomplishment has been launching the Reaction Sorption and Transport (ReSorT) modeling toolkit and building a team of scientists and engineers to foster and grow this modeling and experimental capability. This capability is designed to predict service lifetimes of material assemblies that may age due to material out-gassing and gas-incompatibility issues. We recently tested our model against aging data and found a great match between experiments and models.
What is your educational or career background?
I earned a BA in chemistry from Carleton College (Northfield, Minnesota) and a PhD in physical chemistry from the University of California, Berkeley. I spent a year at Los Alamos National Laboratory between undergraduate and graduate school, and I came to LLNL directly from graduate school. I’ve worked at the Lab for 14 years.
What inspired you to go into your field of work?
I knew I’d be a scientist as long as I can remember; both parents and most of my grandparents were scientists, engineers, doctors, and nurses, so this seemed like the obvious choice. I chose chemistry in undergraduate because I just loved it. I still find it magical and immensely profound that the universe is made up of very simple particles and the only difference between all the tangible things in our universe is how they’re arranged. I chose physical chemistry because it was the only class in undergraduate that truly challenged me—I guess I just wanted to dig deeper and understand the magic of quantum chemistry.
What advice would you give to a new employee at the Lab?
Ask for help and update people around you regularly. If you’re struggling, you may need to bounce ideas off of someone else. If you’re doing great things, you have to tell people so that they can understand what you’ve accomplished.
What do you do in your free time?
I love spending time with my kids. They are funny and clever and ask questions that force me to see the world in new ways, and I’m so proud when I see them accomplish new things that they learned on their own or through us. I love to run; I’ve been running since I was 11 years old. I’ve found that everything is better after a run. I also enjoy cooking, and I really like to travel (especially when I get to run in new places and when my kids come along).

Biography
November 2, 2020
What do you like about working at the Lab?
In a broad sense, I like working at the Lab because of the breadth of research, programs, and people that we have the opportunity to engage with or get exposure to. Over the course of my career at the Lab, I have worked in at least four quite distinct jobs across three directorates and two large programs. I’m very fortunate to have had the opportunity to work on such a wide array of projects while at the same time interacting with a wide variety of people across numerous disciplines. It continues to make things very interesting.
What do your day-to-day work activities include?
I work on a system life extension program in the weapons program. I manage a group of chemistry staff and projects that are focused on characterizing and understanding materials properties and degradation mechanisms in an array of extreme environments. I am very fortunate to have an amazing team of really enthusiastic and talented scientists that lead these complex chemistry studies. There is a great deal of interaction amongst engineers, chemists, and physicists as we proceed through each series of tests and try to figure out what the data is telling us.
What is one project you’re really proud to have worked on?
The one that stands out is the so-called “plutonium aging” project. I was part of a very large, cross-disciplinary team that mirrored a similar team at Los Alamos and had high visibility back at NNSA headquarters and beyond. This was one of the cornerstone projects in the beginning of science-based stockpile stewardship. Besides studying and learning about many aspects of plutonium science, we delivered some very important results and conclusions that were used to help shape stockpile decisions for the future.
What is your educational or career background?
I have a PhD in physical chemistry from the University of Michigan, and my technical areas of focus are in x-ray absorption spectroscopy and actinide chemistry. I spent part of my graduate work at Los Alamos and performed countless experiments at the Stanford Synchrotron Radiation Laboratory. That work led to a joint postdoc appointment with Lawrence Berkeley Lab, an added concentration on x-ray studies applied to actinide systems, and ultimately to a career appointment at LLNL. I’ve worked at LLNL for 30 years.
What inspired you to go into science/your field of work?
I had always liked science and math growing up, and I was actually interested in nuclear energy at a young age. I started out college initially in engineering and surveyed a few other disciplines before converging on chemistry. The draw and migration out to the Department of Energy labs, the West coast, and nuclear disciplines sort of happened accidentally though, perhaps by fate.
What advice would you give to a new employee at the Lab?
Explore as much as you can, and keep your mind and options open. Stay flexible and don’t be afraid to change.
What do you do in your free time?
In my spare time, I do a lot of cycling around the Bay area. I mostly do road biking, and I like long rides into the mountains. I also enjoy traveling, seeing other countries. I follow some professional sports too, but I’m not too fanatical about that.

Biography
October 27, 2020
What do you like about working at the Lab?
I like that there are constant challenges to work on (and problems to troubleshoot), great people to bother with questions, and an environment that largely encourages learning and innovation.
What do your day-to-day work activities include?
I primarily work on understanding material properties under dynamic compression, so on a great day, I’m hitting things with giant lasers in a lab. On a normal (but still pretty good) day, I do lots of planning and lots of technical data analysis of the measurements taken during the aforementioned giant laser experiments. I usually attend a few meetings, and then try to sneak in some paper reading/writing if I can manage it.
What is your educational and career background?
I got my AB (artium baccalaureus, because everything is fancier in Latin) in chemistry at Bryn Mawr College in 2009, and then my PhD from the University of California, Berkeley, in physical chemistry in 2015, working for Prof. Raymond Jeanloz. I actually worked at the Lab as a grad student, starting in about 2010, in the Shock Physics Group (since renamed the Dynamic Material Properties Group and very recently split into two groups), eventually getting hired as a postdoc and then staff. Over the course of my grad work, I gradually shifted more towards high pressure physics, and that is where I’ve ended up today.
What inspired you to go into your field of work?
I enjoy learning and problem solving, and I had a pretty good idea that I wanted to go into research as I was starting college. As to how I specifically ended up in high pressure physics, I can actually trace that to an article in Physics World written in 2009: “Planets under pressure,” which I read while trying to decide between research groups. I thought the work was really cool, and upon realizing that the author was a professor at UC Berkeley, I asked to join his group.
What advice would you give to a new employee at the Lab?
Ask questions. My experience has been that, despite all of my anxiety around asking, people at the Lab are generally very happy to answer questions and talk about their work. This is also a great way to find new projects and meet new people for collaborations.
What do you do in your free time?
Roughly in order of how much of my time is involved: managing a small cat army, reading, playing video games, messing with (read: repairing) my car, and cheesemaking.

What do your day-to-day work activities include?
Mostly I make PowerPoint slides: slides with pictures of target designs, slides with experimental layouts, slides summarizing results. So many slides! I also go to a lot of meetings (WebEx now!) and exchange a lot of emails with the various teams I work with to make experiments happen: the people who design the experiment, the people who run the facilities, the people who make the targets, and the various managers and science stakeholders. I try to spend at least a little time analyzing data and working on a paper every day.
What is one project you’re really proud to have worked on?
I think I’m most proud of my team’s effort to field x-ray diffraction experiments on the National Ignition Facility. It’s been a long time coming to reach complete fruition, but I had the opportunity to be involved almost from the beginning, and it’s been fascinating to watch and participate in this process. We’ve taken over 100 shots, and now the data can be really beautiful....I still get very excited with every shot.
What is your educational and career background?
I studied engineering physics at the University of the Pacific in Stockton, California, and got my PhD in condensed matter physics from the University of California, Davis. I did a postdoc at the Carnegie Institution in Washington, DC, and another at the French Alternative Energies and Atomic Energy Commission in France before joining the Lab in 2010.

Biography
August 26, 2020
What do you like about working at the Lab?
I like the intellectual challenge of trying to invent and optimize an experimental procedure to solve open problems. With many resources both in terms of facilities and highly skilled staff, the Lab is a great place to do challenging experimental science. The Lab is also the leading institution worldwide in my area of research, which uses giant lasers to generate extreme conditions of pressures and temperatures in very brief pulses. This is THE place to do science at the frontiers!
What do your day-to-day work activities include?
I sometimes go to our target preparation laboratory to do hands-on work, but my work is mostly behind my computer and through web meetings. Our experiments on giant lasers like the National Ignition Facility (NIF) involve large teams of people including scientists, engineers, and technicians. Coordinating and choreographing all these activities takes a lot of energy and attention.
I also wear quite a few hats: in addition to leading experiments on Omega and NIF and writing computer code to design experiments and analyze data, I lead a Laboratory Directed Research and Development project, help people design and analyze their experiments with NIF’s VISAR diagnostic, and mentor students, postdocs, and early career scientists. This makes for busy days!
A big fraction of my research targets the inertial confinement fusion effort at the Lab, so I keep up with what others are doing in that area. Finally, as a member of the scientific community, I do synergistic activities like peer-reviewing articles and research grants as well as reaching out through media interviews, NIF tours, and scientific networking.
What advice would you give to a new employee at the Lab?
Go meet people in other areas to learn about what they are doing. Tour the facilities onsite such as NIF. Learn about the Lab’s missions.
What is one project you’re really proud to have worked on?
Overall, I like to think that my contributions are helping the grand challenge of getting ignition at NIF. On a smaller scale, I was fortunate to discover the superionic water ice phase using dynamic compression. Despite the many challenges in designing the experiments, analyzing the data, and getting the work published, this work gathered quite a bit of attention and has been rewarding.
What is your educational or career background?
I studied physics back in France. My PhD was in condensed matter physics, developing new experiments under high pressure and pulsed magnetic fields. I started collaborating with LLNL when I moved to Berkeley to complete my postdoc. I’ve worked at LLNL for 6 years.
What inspired you to go into your field of work?
I like physics as a tool to explain what surrounds us and how things work in general. How I got into laser-driven compression is serendipity, but I really enjoy it because studying the properties of matter at extreme pressures and temperatures is an expanding area of research with many applications, in particular for planetary science and astronomy. We can recreate the conditions inside planets and stars in the laboratory!
What do you do in your free time?

What do you like about working at the Lab?
I enjoy the opportunity to solve materials physics problems in support of national security missions. Experimental, condensed-matter physics offers a wealth of emergent phenomenon, like many branches of physics, but the experiments are often more accessible, permitting rapid hypothesis development and testing. The Lab is serious about solving problems in its broad mission space, so I have had the opportunity to perform research with cutting-edge tools and world-renowned experts, which is a truly exciting way to spend and build a career.
What is one project you’re really proud to have worked on?
Several years ago, I proposed a research project to examine actinide-bearing quantum materials. I am proud of that project for several reasons:
- It allowed me to recruit a top-notch postdoc who is still at the Lab contributing to critical problems.
- It helped to put the finishing touches on a tailored materials synthesis lab that now supports myriad programs across multiple directorates at the Lab.
- Several graduate students, all of whom have taken postdoctoral positions at national labs, performed portions of their thesis under its auspices.
- It produced a number of high-quality papers that reinforced the Lab’s reputation of expertise in actinide science and condensed-matter physics.
What inspired you to go into your field of work?
I first became fascinated with physics in high school. I read Kip Thorne’s Black Holes and Time Warps, and I was hooked on the concept of exploring nature and figuring out how the universe works; astrophysics and cosmology were my introduction to the broad field of physics.
Once I started studying physics, I “discovered” that condensed-matter physics was as rich with weird ideas and objects as astrophysics/cosmology, but these things were much closer to home. I could touch a sample, measure its properties in the laboratory, and then perturb that and do it all over again to see what changed. This was flat-out cool, and it seemed like I could find much less enjoyable pursuits—so a condensed-matter physicist I became.
What is your educational or career background?
I have a BS in physics from Clemson University in South Carolina, and a PhD in physics from the University of California, San Diego. I took a postdoctoral position at LLNL after graduating with my PhD, and I was converted to a staff member working on actinide materials physics and metallurgy. My career path at the Lab has been one of basic and applied science with cross-disciplinary reach. Over time, I gradually shifted from a role of a worker in a Lab to a technical project manager.
What do your day-to-day work activities include?
My daily work scope generally revolves around technical project management. I manage the technical scope and interactions of interdisciplinary groups of scientists engaged in theoretical and experimental research into materials compatibility, component failure, thermophysical properties, mechanical behavior, and chemical change. These seemingly disparate fields overlap in many mission spaces, and those overlaps are often areas where gaps in our understanding become obvious and need to be addressed. Aligning the “right” group of experts to fill in these gaps is both challenging and rewarding.
What advice would you give to a new employee at the Lab?
My advice is really for a new scientist at the Lab: The Lab is a big academic ecosystem in a small footprint. Take advantage of the wide variety of research and tools by collaborating with others on new topics. If you’ve taken a postdoc position here that follows along the path of your graduate studies, then use some of your time to do something different. If you’ve taken a postdoc in a new field, see if you can spend some of your time working on your old field with Lab researchers. You will meet new people, learn new techniques, and you will become a broader and better scientist.
What do you do in your free time?
I am a father and a husband, which means my free time is often spent with the “business” of a family. Part of that responsibility, which is probably a hobby, is being a handyman with car repair, home repair, plumbing repair, etc. When younger, I played guitar and I still have one acoustic guitar. The coronavirus pandemic gave me the time and locality to pick up the guitar once again and try to accompany my son’s piano.

What do you like about working at the Lab?
My two favorite things about working at the lab are the missions and the teams. I love that I have gotten to use my expertise for a variety of applications, some I would have never imagined before coming to the Lab. With each of these applications, I worked toward a truly valuable mission. I now work as part of an interdisciplinary team dedicated to public safety when there is a threat or actual release of contamination, especially nuclear or radiological material, in the atmosphere.
At the Lab, we have a pipeline where an idea or operational need is addressed through cutting-edge research. That research then produces improved processes and capabilities for us to meet our mission. The Lab assembles multidisciplinary teams that provide a collaborative and exciting work environment. I am always being challenged by and learning from the experts with whom I work, and therefore work is never boring!
What is one project you’re really proud to have worked on?
In general, I’m incredibly proud of all work done at the National Atmospheric Release Advisory Center (NARAC). But if I had to pick one particular project that stands out for me, it is leading LLNL’s contribution to DOE’s radiological contingency planning team for the Mars 2020 launch of the Perseverance rover. I never imagined that I would be stationed at Kennedy Space Center in the Radiological Control Center for an Atlas V launch! It has been a wonderful experience to work with a team from DOE, the Department of Defense, and NASA in preparation for the launch.
What is your educational background?
I received a BS in atmospheric science from the University of Illinois at Urbana Champaign, and then a PhD from the University of California, Berkeley, in environmental science, policy, and management, studying ecosystem sciences. I’ve worked at the Lab for 8 years.
What advice would you give to a new employee at the Lab?
I would definitely advise a new employee to learn as much about the Lab’s breadth of work as possible. Attend a seminar outside of your area occasionally. Get involved with networking and/or employee resource groups that will help you meet people from across the Lab. Aside from being interesting, these interactions can lead to innovative multidisciplinary proposals or an opportunity to participate in a cutting-edge project that you wouldn’t otherwise know about.
What do you do in your free time?
I am a mother to 2, so outside of work I spend a lot of time with my kids, enjoying whatever activity they are involved or interested in: sports, museums, theatre, exploring the Bay Area, etc. For “me” time, I challenge myself with the many great day hikes in the Bay Area. My longest so far was a solo hike: 22 miles with 5,000 feet elevation gain along the Ohlone Wilderness trail. I also love to go dancing, to concerts, and to baseball games with my kids and/or friends. Additionally, I enjoy volunteering my free time for various outreach efforts to increase the participation of under-represented populations in STEM fields. I’m a member of the Lab’s Amigos Unidos Hispanics in Partnership and the Lawrence Livermore Laboratory Women’s Association resource groups.

As I continue my career and research experience at the Lab, I feel that I become a better scientist.
What do your day-to-day work activities include?
Most of my time is dedicated to communicating with team members and collaborators to discuss research scope, plans, funding opportunities, results, and challenges. In addition, I communicate with supercomputers to run simulations of materials behavior at the microstructure-level to support many projects associated with energy storage, actinides, corrosion, metal additive manufacturing, and so forth.
What is one project you’re really proud to have worked on?
Since 2015, I have been part of the Hydrogen Materials–Advanced Research Consortium (HyMARC), which is a consortium of multiple national laboratories for solid-state hydrogen storage materials as part of DOE’s Energy Materials Network. HyMARC is a multidisciplinary program under which I have learned so many new things from extensive collaborative research activities with my colleagues at LLNL and other national labs. In particular, my contribution involves defining the roles of mesoscale modeling within the consortium and leading microstructure-level research tasks. I’m really proud of being part of this excellent consortium and working with such brilliant people.

Biography
July 27, 2020
What do you like about working at the Lab?
I love the collaborative nature of LLNL. If I need expertise on a project, there is bound to be an expert here willing to work with me. In addition, we have multiple instruments that are either rare or one-of-a-kind, which allows me to gain unique insights into my study system.
What do your day-to-day work activities include?
I typically spend a few months in the lab growing plants or troubleshooting protocols, and then the rest of my time is spent using bioinformatics to analyze the data and writing manuscripts. Every year I typically get a chance to go out into the field for an experimental soil harvest.
What is one project you’re really proud to have worked on?
I recently published a paper in The ISME Journal on soil metatranscriptomics that looked at how roots alter the decomposition of decaying plant litter. RNA is notoriously unstable and hard to work with in the lab, and sequencing generates a ton of data. It is a unique dataset that I’m really proud to have produced, and I wrote many useful coding scripts along the way that I can now use for other projects.
What is your educational or career background?
I have a BS in environmental science and a BA in religious studies, both from Santa Clara University, an MESM in environmental science and management from the University of California (UC), Santa Barbara, and a PhD in microbiology from UC Berkeley. I’ve worked at the Lab for 7 years.
What inspired you to go into your field of work?
I’ve had a long-standing interest in how plant–microbial interactions can be used for the public good. As a master’s student, I took a bioremediation course that showed that toxin degradation surrounding plant roots is really the work of a community of microbes rather than a single organism. The importance of microbial community interactions stuck with me and inspired me to do a PhD in soil microbial ecology.
What advice would you give to a new employee at the Lab?
Developing relationships at the Lab is a huge part of the experience, and those relationships become your support network both scientifically and personally. Make time for lunch with colleagues and reach out to mentors, your support staff, and your managers when you have questions.

Biography
July 10, 2020
What do you like about your job?
I love that part of my job is to constantly improve myself as a scientist. I’ve gotten to work on a variety of projects, and each one has involved delving into a different type of scientific discipline and developing new skills. The opportunity to contribute to large-scale scientific missions that can’t be accomplished anywhere else in the world, such as my work for the National Ignition Facility, is also very rewarding. I enjoy the campus feel of the site as well. It’s full of different buildings, some historic, some brand new and state-of-the-art, and each one has high-tech instrumentation or other resources devoted to a particular scientific question or technique.
What do your day-to-day work activities include?
Sometimes I know exactly what I need to do and how to do it and can get right to work taking data in the lab, fixing a piece of equipment, or processing data on the computer. Other days, if I’m beginning a new project or working on a particularly challenging problem, I might be at my desk doing background research and reading about scientific topics in journal articles and books or with a co-worker seeking their expertise. I also take time to learn about other people’s science by attending seminars by speakers from within the Lab or outside institutions.
What is one project you’re really proud to have worked on?
It’s not exactly scientific in nature, but I’m really proud of the work I’m doing related to improving the employee experience in PLS. In particular, I’m excited for the launch of a new mentoring program I’ve developed. I think it’s great that the Lab is open to new grassroots ideas from its staff about how to improve workplace culture. It’s also fun to work on a non-science, more people-focused project to balance all the time spent thinking about data and scientific concepts.
What is your educational or career background?
I have a BS in chemistry from New York University, where I also minored in mathematics and Spanish. I then obtained my PhD in chemistry from the University of California, Berkeley. I worked as a postdoctoral researcher at Sandia National Laboratory across the street in Livermore before I came here as a staff member.
What inspired you to go into science?
Interestingly, as a child I never really wanted to be a scientist. I remember in 8th grade science class, my teacher told me I would make a great scientist after doing well on an exam. Although I liked the class, I actually felt sort of offended at the suggestion! I thought of scientists as mostly nerdy older men, and that didn’t sound like me. However, in high school, I became fascinated with how the world works, and I decided I wanted to continue studying science in college.
I also loved the laboratory sections of my high school and college science courses. I thought they were the most fun way to spend a class period. I was also motivated by the promise science holds to solve the world’s problems, from curing disease to providing for a sustainable future. I chose chemistry because it’s thought of as the “central science” in that it connects other fields, such as physics and biology.
What advice would you give to a new employee at the Lab?
Explore as much as possible. The Lab is quite large both in terms of people and buildings. There are projects ranging across every type of science and engineering here, and employees are free to get involved in new things. I also recommend asking questions. Many people have worked at the Lab for over 20 or even 30 years. It’s important to speak up and ask if you don’t understand something, whether it’s what one of the many three letter acronyms used here stands for, the motivation behind a particular Lab mission, or a specific technical topic.
What do you do in your free time?
I try to take advantage of living in California and the Bay Area as much as possible. I take road trips across the state often to go camping at mountains, lakes, and beaches. I also love going to museums, art galleries, concerts, and restaurants in San Francisco. I spend at least one day per month volunteering. Another big hobby I have is gardening, and I even have a garden plot on site here with the Lab’s Gardening Networking Group. I’m also a member of the Lawrence Livermore Laboratory Women’s Association.

Biography
July 7, 2020
What do you like about working at the Lab?
Being a part of LLNL, simply as an intern, has been an amazing experience both professionally and scientifically. I had the opportunity to intern at the Lab as a Seaborg fellow last summer, and I’m currently participating in a virtual LLNL internship. The Lab itself is such a cool place because it contains some of the best and brightest minds. Not to mention, Livermore (& California) itself is a neat place to live.
What do your day-to-day work activities include?
Currently, my internship experience is unique because it is virtual. My day-to-day consists of Excel spreadsheets and relating vast amounts of data relevant to nuclear forensics. Finding an effective way to store, manage, and query the data is what I am currently working on for the Lab. Last year, when I was working at the Lab, a typical day included method development and subsequent measurements of fuel pellets using optical profilometry and digital microscopy.
What is one project you’re really proud to have worked on?
The internship I conducted at the Lab was very transformative for my graduate school career, as I was able to take a step back from my dissertation work and travel to the Lab. My project aim was to create a methodology for measuring the surface roughness on fuel pellets using optical techniques. For nuclear forensic science, this work could provide clarification on the usefulness of surface roughness as a forensic signature. With the help of my mentor, Naomi Marks, I was able to conduct this research from start to finish. I felt confident in the skills I had learned in my first few years of graduate school and was able to really enjoy the process.
What is your educational or career background?
I got my BS in geology at Lock Haven University, and I am currently pursuing my PhD in earth sciences at the University of Notre Dame. My dissertation work focuses on the microscopy and spectroscopy of solid-state actinide materials. I was accepted as a Seaborg fellow last year and loved it so much that I knew I wanted to come back for a second summer. My hope is to pursue a postdoctoral fellowship at the Lab after graduation.
What inspired you to go into your field of work?
As a geology major in undergrad, I became keenly fascinated with all things nuclear energy. It was at a national geology conference that I met my now PhD advisor, Amy Hixon, who led me down a path I did not even know existed at the time: nuclear forensics. In a way, some of what has happened in my early career has been a bit serendipitous. With that said, I have always loved microscopy and the idea of characterizing the macroscopic appearance and microstructure of materials. Funny enough, I still get to use scanning electron microscopy in graduate school, just as I did in undergrad.
What advice would you give to a new employee at the Lab?
As a (returning) intern, my advice would be never to lose your enthusiasm, and take any opportunity to learn about what goes on at the Lab other than your own research. There are awesome tours available to interns and from my experience, everyone is always so nice.
What do you do in your free time?
I love to travel. The national parks, specifically the Grand Tetons, is probably my favorite place in the world. Italy also has a special place in my heart because I love the food (& the wine). I watch Harry Potter at least once a week, and I enjoy strength training.
July 7, 2020
What do you like about working at the Lab?
I get to work on exciting, large-scale projects with a diverse group of experts in their various sub-fields.
What do your day-to-day work activities include?
All too many meetings, but when I get to sit at my desk, I develop computational models, write code to more effectively run simulations, and run and analyze molecular dynamics simulations on some of the world’s largest high-performance computers.
What is one project you’re really proud to have worked on?
We have been developing in silico assays for measuring drug-induced changes in membrane properties. This is of great importance, as many of the key proteins that regulate cell function are membrane embedded, and their function can change when you alter the membrane environment. Therefore, drugs can have undesirable off-target effects on a range of proteins without even directly interacting with them—a mechanism we can now test in silico during drug design, even before the drug lead is synthesized.
What is your career background?
I’m a computer scientist turned experimental biophysicist turned computational biologist.
What inspired you to go into your field of work?
Curiosity about how things work. Biology in particular always appeared so messy, and still does, but little by little we discover more about the underlying principles.
What advice would you give to a new employee at the Lab?
Explore—the Lab is large, with an amazing amount of exciting and diverse research.
What do you do in your free time?
Currently, I mostly play with my 7-month-old daughter, but I also love to hike and read.
Are you a member of any employee resource groups?
I’m a member of the Early Career Employee Resource Group.

What do you like about your job?
I love the wide range of activities I get to work on. I collaborate with a lot of people around the Lab, and it feels like I’m constantly learning about new techniques and developing new skills. I’m involved in many different aspects like postdoc mentoring, private partnerships, proposal writing, and of course research.
I enjoy working with the Lab’s devices. We cool our circuits down to temperatures that are 100 times colder than space, and then we probe them with tiny microwave fields to try to access their quantum mechanical properties.
What do your day-to-day work activities include?
Every day seems to be different. I can spend one day programming, another day wiring up a dilution refrigerator, and the next day writing up a patent.
What is your educational or career background?
I’ve always wanted to be a physicist. I studied physics at Foothill College, and finished my undergraduate degree at UC Berkeley. I then went to UC San Diego and studied condensed matter physics with Professor Ivan Schuller. There I studied the interactions of nanomagnets with superconductors and had my first exposure to quantized phenomena. I then took a postdoc position at the Laboratory for Physical Sciences at the University of Maryland, where I studied the strange properties of materials when in quantum mechanical environments.
Once I finished my postdoc, I learned that LLNL was starting up a new quantum computing program, and the notion of starting in a lab at the ground floor was too tempting to pass up.
What is one project you’re really proud to have worked on?
A few years ago, I came up with the idea of using a phononic bandgap to block the energy loss in quantum circuits due to the environment. I received a feasibility study, and after running multiple simulations and performing some fabrication runs, we determined that it’s a viable research direction. We now have a patent and are collaborating with UC Los Angeles to develop this new technology.
What inspired you to go into science/your field of work?
I’ve always enjoyed technical challenges and figuring things out. Physics is especially fun because there is always a puzzle you have to solve. Quantum physics is a particularly challenging area—materials in quantum computing environments behave in strange and unintuitive ways. Unlocking their secrets requires working at cryogenic temperatures and at radio frequencies and using statistical tools that can extract information from collective effects.
What advice would you give to a new employee at the Lab?
Talk with people and make new friends. You never know when you might find a project that overlaps with your expertise and you can start a collaboration.
What do you do in your free time?
Gaming and taking care of my 2-year-old son. I’m a member of the tabletop games networking group at LLNL.

I also really like living in Livermore—it has great restaurants, nice people, is very walkable/bikeable, and has good access to hiking. Finally, working at LLNL gives me access to amazing computational resources and professional opportunities.
What do your day-to-day work activities include?
I use computer modeling to study climate change. On a typical day, I write computer code, solve math problems, think about rain storms, manage a team, and perhaps give a talk or work on a paper.
What is one project you’re really proud to have worked on?
I’m currently leading a project aimed at creating a new numerical model of the atmosphere. This model will have much finer spatial resolution than previous models, which should make it more accurate and trustworthy. This project is equal parts atmospheric physics (choosing realistic process representations and good questions to answer with the model) and computer science (building a model which runs really fast on the world’s newest and biggest supercomputers). It is, to our knowledge, the first global climate model written in C++.
What is your educational and career background?
I got a BS and MS in mathematics from Western Washington University, and then a PhD in atmospheric sciences from the University of Washington. I came to LLNL as a postdoc 11 years ago and never left.
What inspired you to go into your field of work?
Climate science is a unique blend of geophysics, computer science, numerical analysis, statistics, and communication skills, which is a good fit for my jack-of-all-trades background. Also, I care deeply about the future of our planet. I feel lucky to get paid for saving it.
What advice would you give to a new employee at the Lab?
Get to know a lot of people—you never know who will have great advice or an opportunity for you. Volunteer to help out wherever you can—this will lead to more opportunities and increase your value to the lab.
What do you do in your free time?
In my free time, I like to explore the natural world under human power. I’ve skied across the Sierras and off the summit of many peaks in California and Washington. I’ve biked from Seattle to San Francisco and back as well as north–south across Germany. These days, I spend most of my free time kayaking. I’ve been on kayak expeditions in Mexico, Belize, England, Croatia, Thailand, and British Columbia, but I spend most of my time exploring the coast and rivers of California.

What do you like about working at the Lab?
I love puzzles and dislike being bored. At the lab, I get all the puzzles (and the resources to solve them), and I haven’t been bored yet. I get to do all of this fun puzzle solving with great coworkers and contribute to national security at the same time. It’s a great combo.
What do your day-to-day work activities include?
I smash stuff, really hard, to see what it does.
In normal times, my days vary. On any given day, I may be traveling for an experiment or meeting; setting up, operating, or running experiments; designing experiments/studies/diagnostics; meeting with engineering to move those designs to reality; simulating experiments; analyzing data; writing reports/papers; interviewing candidates; or planning the next stages of work.
What is one project you’re really proud to have worked on?
That’s tough, as I have two favorites. One project studied the shock response of granular materials on the local and long scales using x-ray imaging and diffraction methods. We were one of the first groups to image shocked materials during the shock using Argonne’s Advanced Photon Source. This let us measure the response of few-grain and many-grain samples to understand how force transmits, how the different grains break, and how phase transitions may differ in these samples compared to their bulk counterparts.
The other project is one I’m working on currently to measure temperature in shocks. I think of this as putting the ‘thermo’ back into thermodynamics—there’s almost no data, so we have to guess (or at best, estimate) important parts of our equations of state, even for materials that we otherwise know a lot about. This gap is holding our community back. This is the project that gets me up in the morning and keeps me up at night, because it’s really tough.
What inspired you to go into science?
My mom was an entomologist, so science was always on my radar. It was just the two of us, so I spent a lot of time in the lab and in the field with her. When I wasn’t mosquito bait, I was busy looking through microscopes. I explored various fields of science from there, and ended up doing shock physics kind of by accident.
When I graduated in mid-2008, I was six months pregnant and the economy was in free fall—getting a job right away didn’t happen. LLNL recruited my husband and me at the same time, so I ended up changing fields just trying to make sure we could work in the same city.
What is your educational or career background?
I got my BS in chemistry from Caltech (Pasadena, CA) in 2003, and my PhD in physical chemistry from the University of Texas (Austin, TX) in 2008. While a grad student, I had a summer fellowship at Pacific Northwest National Laboratory, which confirmed for me that I wanted to work at a national lab or NASA.
What advice would you give to a new employee at the Lab?
Network like mad. Find your org chart and pick a name, if you need to. If you’re an introvert, network extra. If you’re a postdoc or student, the lab lets you really explore and be creative with more resources than you had in school, so enjoy the time and make the most of those opportunities.
What are your hobbies?
Reading, weaving, spinning, art, baking, home repair, dog training, and volunteering.

In 2001, I was asked to lead the effort to get the first International Organization for Standardization (ISO) 17025 accreditation for PLS and Global Security’s Forensic Science Center (FSC). This accreditation was a requirement for the FSC to be a designated lab for the Organisation for the Prohibition of Chemical Weapons (OPCW). At the time, the FSC was one of only two designated laboratories in the United States.
The OPCW is headquartered in The Hague, Netherlands, and is the implementing body for the Chemical Weapons Convention. It was a major accomplishment. Since that time, the ISO 17025 accreditation has been expanded to include the FSC Rad Forensic efforts.
I am proud that the accreditation continues today and I have the opportunity to work with exceptional people.
