Dr. Stéphane Ethier is a Principal Computational Physicist at the Princeton Plasma Physics Laboratory. He is Deputy Head of the Computational Plasma Physics Group (CPPG) and leads the High Performance Computing effort. He obtained a B.Sc. and M.Sc. in physics from the Université de Montréal in Montreal, Canada, and a Ph.D. in 1996 from the Institut National de la Recherche Scientific (INRS) in Varennes, Canada. His thesis project in laser-matter interaction highlighted the effects of high intensity, ultrashort laser pulses on solid-density plasmas using electron kinetic simulations. Prior to his appointment at PPPL, Dr. Ethier was a research associate in the Applied Physics group of the Mechanical and Aerospace Engineering Department of Princeton University, working on the development of a collisional-radiative code for X-ray laser applications.
Dr. Ethier's work covers all aspects of high performance computing in support of PPPL's large-scale scientific codes. His main research focus has been on global gyrokinetic particle-in-cell codes for the study of micro-turbulence instabilities in tokamaks. His other interests cover extreme-scale computing, shared memory parallelism with OpenMP, GPU programming with OpenACC, Advanced MPI, one-sided communication, etc.
Dr. Ethier served as the chair of the National Energy Research Scientific Computing Center (NERSC) Users Group Executive Committee from 2007 to 2014. He also served on the Oak Ridge Leadership Computing Facility Users Group Executive Board and on the NERSC Policy Board.
