Lawrence Livermore National Laboratory

The Physical and Life Sciences Directorate (PLS) is comprised of five divisions.

Atmospheric, Earth, & Energy Division (AEED)

LLNL’s missions in national security, energy security, and fundamental science require robust, multidisciplinary research and development in atmospheric, Earth, and energy sciences.

Materials Science Division (MSD)

MSD conducts research and development at the intersection of chemical and nuclear science in support of LLNL's national security missions. MSD personnel provide expertise in organic/inorganic, synthetic, analytical, computational, nuclear, and environmental chemistry, to solve problems in stockpile stewardship and other national security programs.

Physics Division (Physics)

The Physics Division conducts frontier physics research and development in fields ranging from astrophysics and planetary science, to atomic, condensed matter, plasma and high energy density physics. This work includes advanced science and technology development in optical and x-ray science, detectors, predictive modeling and simulation, dynamic/static extreme environments, lasers, space, and fusion. These research and development activities place LLNL at the leading edge of 21st century national security missions.
