Tom Epperly joined the Center for Applied Scientific Computing (CASC) in March 2000 as a computer scientist. His research interests focus on software frameworks and standards for large-scale computational modeling of physical systems. He is also interested in object-oriented programming, computer languages and representations for large-scale models.
As Components Project Leader, Tom is one of the lead architects of Babel, the high-performance language interoperablity tool. He is also the principal investigator for a CS Scientific Application Partnership (SAP) with FACETS, a project to develop a high-performance, parallel framework for integrated modeling of the core, edge, and wall regions of ITER-scale Tokamak fusion reactors.
Tom holds a B.S. in Chemical Engineering from Carnegie-Mellon University, and a Ph.D. in Chemical Engineering from University of Wisconsin. At CMU, Tom worked on ASCEND, an object-oriented language for building large systems of equation-oriented models. At University of Wisconsin, he worked on a parallel branch and bound algorithm for solving nonconvex nonlinear programs.
Following graduate school, Tom completed a post-doctoral year in the Centre for Process Systems Engineering at Imperial College; then he moved to Aspen Technology, Inc. At Aspen, he worked on a software framework for building and solving large sparse nonlinear programs.
