Biosciences & Biotechnology

LLNL’s Biosciences & Biotechnology Division lies at the intersection of biological, physical, and engineering sciences. We apply an understanding of fundamental biology to predict and counter emerging biological and chemical threats and to solve problems in health and environmental security.

LLNL’s cutting-edge technologies, in combination with experimental and computational methods, help us solve important national problems in biosecurity, human health, and environmental biology. We perform fundamental and applied research in areas such as genomics, molecular toxicology, nanotechnology, host–pathogen biology, structural biology, genetics, microbial systems, and medical countermeasures. We employ world-class facilities and up-to-the-minute advances in the biosciences, physical sciences, nanotechnology, and imaging and measurement science to solve problems that matter.

Our multidisciplinary staff focus on integrating experimental and computational tools to understand complex cellular systems, testing and expanding our understanding of cellular mechanisms, and using our knowledge to provide solutions for countering current and emerging threats.

Genomics

Group leader: Crystal Jaing

The Genomics group develops innovative bioassays to rapidly detect infectious agents and other pathogens to support public health, food safety, and drug safety. We apply expertise in genomics, bioinformatics, virology, and molecular biology to characterize pathogens, develop assays to detect microbial agents in the environment, identify novel biomarkers for diagnostics of infectious diseases, characterize unknown and emerging pathogens, and study the evolution and virulence mechanisms of key viral and bacterial threat agents.

Microbiology and Immunology Group

Group leader: Nicholas Be

The Microbiology/Immunology group is a diverse group of scientists with expertise in microbiology, virology, immunology, infectious disease pathogenesis, and microbiome science. We conduct research on host–pathogen interactions and microbial communities with a focus on biothreats and military medicine applications. Among our projects are studies of host immune responses during infection using a combination of in vitro and in vivo approaches, vaccine and therapeutic development, viral evolution and cross species transmission, and integration of assay design with simulations and machine learning.

Human Health Sciences Group

Group leader: Heather Enright

The Human Health Sciences group conducts basic science and applied research on the mechanisms of action of the effects of chemicals and drugs in humans, how gene expression is regulated, and bone metabolism and fracture repair. We also focus on understanding the damage caused by radiation exposure, developing new technology for biosurveillance of outbreaks of infectious diseases, and accelerating the development of medical countermeasures. Our studies help us understand how people respond to drugs and chemicals, how they vary in their response, and how to prevent deleterious effects.

Translational Immunology Group

Group leader: Matthew Coleman

The Translational Immunology group is a diverse group of scientists with expertise in immunobiology, cellular biology, biotechnology, and nanotechnology. We are conducting research on vaccine development and understanding inflammatory processes and diseases. Our group has developed novel nanotechnology tools for the synthesis and characterization of immunomodulatory proteins, nucleic acids, and small molecules with applications toward national biosecurity interests. Among our projects are studies of targeted immune responses using a combination of in-vitro and in-vivo approaches that focus on protein and nucleic acid vaccines, as well as small molecule immune modifiers.

Biochemical and Biophysical Systems Group

Group leader: Felice Lightstone

Scientists in the Biochemical and Biophysical Systems group use cutting-edge, multi-scale, in silico simulations to tackle problems in biology. We use a wide range of computational biology methods that employ LLNL’s high-performance computing resources to simulate systems from sub-atomic scale to population level. These methods include atomistic and coarse-grained molecular dynamics, quantum simulations, constraint-based genome-scale simulations, reaction-transport dynamic simulations, and agent-based, whole-organ, and pharmacokinetics/pharmacodynamics models.

We develop new computational methods to describe and predict biological systems. In addition, we combine experimental efforts with physics-based simulations and statistical and machine-learning models to accelerate the design and development of safe and effective therapeutics. Overall, we seek predictive understanding of protein-mediated processes related to critical missions of LLNL, including bioenergy, medical countermeasures, and new materials.

Advanced Biotechnologies Integration Group

Group leader: Jeff Drocco

The Advanced Biotechnologies Integration group develops and deploys high-impact operational capabilities to sample, characterize, and recover from biological events. Our diverse group includes expertise in environmental sampling, molecular biology, microbiology, ecology, clinical testing, antibody production, chemistry, and quality assurance. We strive to improve the time-to-results, efficiency, sensitivity, and specificity of operations used to mitigate biological threats.

Our research involves developing rapid viability methods for biological agents, fielding a clinical testing laboratory for COVID-19 response, deploying mobile biological laboratories for special event monitoring, and developing methods for detecting biothreats in complex environmental samples. Several members of our group are also applying their technical expertise to help with LLNL’s Life Extension Program (LEP) in the Strategic Deterrence Directorate.
