Cameron G.R. Geddes is the Director of the Accelerator Technology and Applied Physics Division at Lawrence Berkeley National Laboratory. He leads the division in inventing, developing, and deploying particle accelerators, lasers and photon sources to extend the frontiers of science, as well as systems for fusion and related areas of applied physics. His research focuses on study of laser driven plasma waves to create next-generation compact particle accelerators for high energy physics and and photon sources, advanced laser technologies, and high energy density science. Related research spans nuclear nonproliferation, large-scale simulations, magnetic and inertial fusion, and high energy density science. He has held past positions at Lawrence Livermore National Laboratory, Polymath Research, and Swarthmore College. He is a Hertz Fellow and a Fellow of the American Physical Society, and has received from the Society the John Dawson Award for Excellence in Plasma Physics Research, the Marshall N. Rosenbluth Outstanding Doctoral Thesis Award, and the Leroy Apker Undergraduate Thesis Award.
