Thomas Epperly is the Components Project Leader in the Center for Applied Scientific Computing (CASC) at the Lawrence Livermore National Laboratory (LLNL). His research interests focus on language interoperability and component technology to facilitate large-scale computational modeling of physical systems. At LLNL, he has worked as co-architect of Babel, the R&D 100 award winning language interoperability technology, and as the Computer Science Group Leader. Dr. Epperly, a Department of Energy Computational Science Graduate Fellow, earned his PhD in Chemical Engineering from the University of Wisconsin and his B.S. in Chemical Engineering from Carnegie-Mellon University. As a post-doc in the Centre for Process Systems Engineering at Imperial College in London, he worked on global optimization algorithms for reactor design under uncertainty. After his post-doc, he worked for Aspen Technology, Inc. on an equation-oriented modeling framework for real time optimization of chemical plant operations.
