Choong-Seock Chang is the head of the multi-institutional multi-disciplinary US SciDAC Center for Edge Physics Simulation (EPSI), headquartered at Princeton Plasma Physics Laboratory, Princeton University, awarded by US Department of Energy, Office of Fusion Energy Science and Office of Advanced Scientific Computing Research, jointly. SciDAC is an acronym for Scientific Discovery through Advanced Computing. The center activities include fusion physics, applied mathematics and computer science. He was also awarded with another multi-institutional multi-disciplinary SciDAC Center for Plasma Edge Simulation (CPES) during 2016-2011, previously headquartered at Courant Institution of Mathematical Sciences, New York University. He holds the position of Principal Research Physicist at Princeton Plasma Physics Laboratory and a Joint (adjunct) Professorship with Department of Physics, Korea Advanced Institute of Science and Technology. By joining Princeton University, Choong-Seock Chang retired from faculty of Courant Institute of Mathematical Sciences, New York University, and Department of physics, Korean Advanced Institute of Science and Technology. He received his physics B.S. degree in 1975 from Seoul National University and physics Ph.D. degree in 1979 from the University of Texas at Austin. He started out his scientific career as a research staff at General Atomics in 1979. He is a Fellow of the American Physical Society, with broad and in-depth research experience in fusion plasmas, industrial plasmas, strongly interacting biophysics system, nonlinear chaos phenomena, and radio frequency heating. His current worldwide leadership is in the extreme scale super-computing research activities on multiscale turbulent self-organization and transport physics in magnetically confinement plasma. He has been serving in numerous national and international advisory and executive committees. He headed the Korean tokamak physics design team activities for the Korean Supercomputing Tokamak Research facility (KSTAR) in 1995-1998, which led to the world’s most advanced tokamak research facility in operation today, and chaired Korean Physical Society Plasma Physics Division in 1998-2000. His close collaborators include not only theoretical and experimental plasma physicists, but also internationally prominent applied mathematicians and computer scientists. He has over 150 publications in peer reviewed internationally recognized journals, and has given countless invited talks, keynote speeches and tutorial lectures at major scientific conferences. He has produced over 15 Ph.D.’s and trained similar number of postdoctoral scientists.
