John R. Cary is a professor of physics at the University of Colorado at Boulder, and he is CEO of Tech-X Corporation, a Boulder, CO research corporation, which he co-founded in 1994. At the University of Colorado, Prof. Cary has served as department chair, center director, and Area Teaching Scholar for the Natural Sciences. Tech-X Corporation has 34 employees with expertise across a broad range of physics and computer science. Professor Cary received a B.A. in mathematics and a B.A. in physics from the University of California at Irvine. He received an M.A. and a Ph.D. in physics from the University of California at Berkeley. His prior positions were at the Los Alamos National Laboratory and the Institute for Fusion Studies at the University of Texas. Professor Cary’s interests are in plasma physics, beam physics, and nonlinear dynamics, as well as in the application and development of modern computing techniques to computational physics. He has more than 100 refereed journal articles on various aspects of physics and computation. His recent work includes architecting and developing VORPAL, an object-oriented, highly flexible plasma simulation application that computes with scaling good to 4000 processors, yet can and does produce significant results on single processors due to its arbitrary dimensionality. This work illustrated that a properly designed, large-scale numerical application could be object oriented and written in C++ without any performance penalty. Professor Cary has chaired multiple national committees for the Division of Plasma Physics of the American Physical Society (APS) and served on many others for the APS, of which he is a fellow.
