From actinides and architected materials to polymers and energetic materials, LLNL’s Materials Science Division (MSD) is constantly innovating in materials science.
Our multidisciplinary teams strive to create novel materials for security and energy applications and to understand the properties and performance of materials subjected to mission-relevant conditions.
We use state-of-the-art characterization technologies coupled with modeling and simulation to meet current and future national security needs, executing world-leading, discovery-class research in the fields of materials physics and chemistry. With these capabilities, MSD supports a broad range of existing and emerging LLNL programs.
Understanding how materials behave in various conditions drives MSD scientists to develop new materials for diverse applications:
Other efforts include innovations in materials assembly and processing to capture emergent properties at the nano-, meso-, and macroscale, as well as exploiting our characterization and synthesis expertise to optimize and scale the production of functional materials.
As a recognized and trusted leader for innovative, timely, and effective materials science solutions, MSD works closely with collaborators both inside and outside LLNL on a number of key national security and energy-focused initiatives. We also mentor the next generation of materials scientists through internship and postdoctoral fellowship programs.

With access to world-class facilities and instrumentation, our researchers specialize in the synthesis, characterization, integration, and application of composites and soft matter.
Group leader: Scott McCall
With expertise spanning the gamut from surface science to magnetism to metallurgy, our scientists support global and national security missions through experimental work on actinide and lanthanide materials. We strive to understand the structural, chemical, mechanical, magnetic, and electronic properties of 4f- and 5f-electron systems. We also maintain capabilities for handling and preparing air-sensitive and radioactive samples (including transuranic materials).
Group leader: Kiel Holliday
We apply atomic-scale mechanistic understanding of chemical phenomenon to link material synthesis and manufacture with properties and performance. Our chemical operations expertise supports the Nuclear Materials Program within Weapons Technology and Engineering.
Group leader: Yong Han
We conduct research at the intersection of chemistry, materials science, and chemical engineering. We synthesize, characterize, and process diverse materials including organic compounds, composites, and inorganic materials at various length scales spanning the nano-meso-macro regimes. The breadth of our expertise in materials synthesis, characterization, integration, and application allows us to provide materials related solutions and expertise in energy and national security applications.

Our researchers specialize in the modeling and experimentation surrounding the development, characterization, and effectiveness of energetic and reactive materials. We explore the energy released during energetic chemical reactions, such as in comparing composites to single-molecule materials, the mechanical response of those materials, and their long-term aging and chemical compatibility. We improve the safety, performance, and understanding of energetic materials and investigate advanced manufacturing techniques and new materials development.
We have created novel energetic materials, scaled them up to custom feedstocks, manufactured them into unique systems, and tested their performance.

We specialize in modeling and experiment surrounding the development, characterization, and surety of high-explosive materials.
Group leader: Rick Gee
We employ static and dynamic high-pressure techniques to probe chemical changes in matter that occur at pressures that challenge the bonding energy of atoms. We tightly couple modeling and experimental efforts to understand chemical decomposition and synthesis that occur under extreme conditions.
To further LLNL’s national security mission, our scientists develop novel materials and precision assembly and characterization techniques for experiments at the National Ignition Facility (NIF) and other high-power laser facilities.

Group leader: Joe McKeown
We use pulsed x-ray radiography, diffraction, and optically based velocimetry and in situ techniques to research the response of materials to strongly driven conditions. Our in situ techniques make time resolved measurements of materials structure using a Dynamic Transmission Electron Microscope (DTEM), which characterizes materials at the length scale of nanometers and timescale of nanoseconds. We employ various platforms including gas guns, high energy pulsed lasers, and high explosives to yield information on structural response, dislocation nucleation and glide, twinning, and phase transformations.
Group leader: Brandon Chung
Our multidisciplinary expertise in plutonium metallurgy and analytical chemistry allows us to use a comprehensive suite of analytical techniques within a nuclear facility to characterize special nuclear materials and develop technologies to deliver responsive solutions.
Using high-performance computing resources, our experts build versatile massively parallel computing capabilities for investigating chemical, electronic, structural, and kinetic properties of materials. These tools address critical challenges in clean energy, nuclear nonproliferation, and extreme-condition science.
To support both basic science and programmatic missions, we strive to ensure that our computational resources provide reliable, accurate results for use in theoretical and experimental research and discovery.
