Roger Falcone has been a Physics professor at Berkeley since 1983, and chaired the Department from 1995-2000. He is an affiliated faculty member of Berkeley's Energy and Resources Group and Applied Science and Technology Program, and has been the director of the Advanced Light Source x-ray synchrotron facility at Lawrence Berkeley National Lab since 2006. Falcone received his A.B. in Physics (1974) from Princeton, and Ph.D. in Electrical Engineering (1979) from Stanford, and was a Marvin Chodorow Fellow in Applied Physics (1980-83) at Stanford. He chairs the Advisory Board for Paul Scherrer Institute in Switzerland; is director of the UC Institute for Materials Dynamics at Extreme Conditions; advises the nation’s national security laboratories; and is incoming Vice-President of the American Physical Society (2016). Falcone chairs the faculty advisory committee for the Lawrence Hall of Science, UC Berkeley's public science center. Falcone is a Fellow of APS, OSA, and AAAS.
Falcone's research primarily involves the interaction of intense and short pulse light and x-rays with matter. He has co-authored over 150 publications in fields ranging from ultrafast science to plasma physics. He uses lasers to create and probe plasmas, to study dynamics in molecules and materials, and to compress matter to pressures near a billion atmospheres. His experiments range from those involving single students in university labs, to teams of scientists at large, national laboratory facilities, including the NIF fusion laser at LLNL, the ALS x-ray synchrotron at LBNL, and the LCLS x-ray laser at SLAC.
