John D. Ramshaw, Ph.D. Research Professor

     Dr. Ramshaw joined Portland State University in September 2007 as a Research Professor in the Department of Physics.  He previously  held theoretical research positions in the Los Alamos, Lawrence Livermore, and Idaho National Laboratories.  His research has been concerned with various topics in equilibrium and nonequilibrium statistical physics, and in the analytical and computational dynamics of fluids and plasmas.  He has made seminal contributions to the molecular theory of dielectric fluids, and to the theory of multiphase and multicomponent fluids.  He served as project leader and principal investigator for the development of several advanced computer programs for simulating the multidimensional flow of multicomponent fluids and plasmas with chemical reactions, including the APACHE, KIVA, and LAVA codes.  KIVA is widely used by the automotive industry to simulate internal combustion engines, and received a commendation by the Secretary of Energy and an Energy 100 Award.  Dr. Ramshaw has published extensively in the archival journal literature, and has served as a reviewer for numerous technical journals, professional organizations, and funding agencies.
