Biographical sketch for @RobertRyne

Dr. Robert D Ryne received his B.S. in Physics in 1981 at UC Berkeley and his M.S. and Ph.D. in Physics in 1987 at the University of Maryland. His Ph.D. dissertation, directed by Prof. Alex Dragt, was on the "Lie algebraic treatment of space charge." During his career Dr. Ryne held positions at Lawrence Berkeley National Laboratory, Los Alamos National Laboratory, and Lawrence Livermore National Laboratory. In the 1990s Dr. Ryne was a pioneer in the use of massively parallel computers for modeling beam dynamics in particle accelerators. He led the development of the first version of the IMPACT code. Later he proposed how split-operator methods could be used for multi-physics accelerator modeling, and he combined high-order optics effects with space-charge effects in the MaryLie/IMPACT code. He has had leadership positions in several US Department of Energy (DOE) programs. At Los Alamos he was the head of the Los Alamos Accelerator Code Group. He was co-leader of a DOE Grand Challenge in Computational Physics and a DOE Scientific Discovery through Advanced Computing project. He was the Level 1 manager for Design and Simulation in the US DOE Muon Accelerator Program (MAP). In addition to modeling space-charge effects, Dr. Ryne has significant experience in modeling radiative effects in high intensity electron beams. He is the developer of the LW3D code and the Shambala code to study radiative phenomena using a Lienard-Wiechert approach. He has been involved in the international Computational Accelerator Physics community for more than 30 years. He helped initiate the International Computational Accelerator Physics (ICAP) conference series and was Chairperson of ICAP 2009. He is the moderator of the acc-ph section of arxiv.org .
