Adam Schwartz is the Division Leader for Condensed Matter and Materials Division in the Physical and Life Sciences Directorate at the Lawrence Livermore National Laboratory in Livermore, California. His research focuses on the fundamentals of plutonium aging, phase transformations and phase stability of Pu alloys, electronic structure of actinide elements, and dynamic properties of materials.
He holds B.S. and M.S. degrees in Metallurgical Engineering from University of Pittsburgh (Pittsburgh, PA), and a Ph.D. degree in Materials Science and Engineering from University of Pittsburgh. Before accepting the position as Division Leader, he was the Deputy Program Leader for Dynamic Materials Properties within the Science Campaigns and the Deputy Program Leader for Physics and Engineering Models in the Advanced Simulation and Computing Program. Prior to these activities, he led the Plutonium Aging and Pit Lifetime Program at LLNL, was Major Technical Effort Leader for Pu aging, was principal investigator on numerous projects, and was a post-doctoral research associate at LLNL.
