Gilbert received his Ph.D. in Physics at The Ohio State University in 1989, and for the next 27 years worked at LLNL as a Staff Scientist, Group Leader for Cryogenics, Group Leader for High-Energy-Density (HED) Shock Physics, Associate Division Leader in Physics, Director for the Center of HEDS, and Member of the Distinguished Technical Staff. He helped build and worked with several world-recognized groups exploring different aspects of HEDS and Stockpile Stewardship, hiring 34 scientists. In 2016, he moved to the University of Rochester, where he is the Tracy Hyde Harris Professor of Physics and Mechanical Engineering, and Associate Director at the Laboratory for Laser Energetics. He is working with an outstanding team of scientists and students at Rochester, LLNL, and institutions worldwide, exploring and documenting the microphysics of HEDS (curriculum and research). He has >260 publications; an h-factor ~65; led many HEDS workshops, conferences, sessions at DPP, summer schools, courses, and advisory committees; and has directed ~25 students. He has received several awards including the Bridgman Award, APS Fellowship, APS award for Excellence in Plasma Physics, U.S. DOE Weapons Recognition of Excellence Award, NNSA Award for Excellence in the SSP, and NNSA Science and Technology award.
