Center for Applied Mathematics and Statistics (CAMS) Main Research Areas

CAMS members conduct research in a broad range of areas of applied mathematics, using, in particular, the techniques of scientific computation/numerical analysis, applied analysis and analysis of PDEs, mathematical modeling and asymptotics, dynamical systems theory, and statistics. The focus of CAMS research is roughly divided into five application areas (with significant overlap), listed below.
