Mission Statement

Joseph P. Hooper
Assistant Professor of Physics
Ph.D. Physics, Tulane University, 2006

Dr. Hooper joined NPS in 2011, following five years as a Research Physicist for the Navy at NSWC Indian Head. His research interests include explosives, shock physics, high-velocity impact, and material behavior at extreme conditions. Current projects include atomistic simulations of new explosives and nanomaterial-reinforced armors, as well as experimental work in ballistic impact and fragmentation.
