Jim currently is the Senior Manager of the Computational Sciences and Math Group, which consists of four departments: Computational Mathematics, Computational Multiphysics, Computational Multiscale, and Computational Science. Jim previously served as manager of the Optimization & Uncertainty Quantification Department.  A significant part of Jim's role is to ensure delivery and support of the group's broad computational science capabilities for Sandia's internal mission-focused customers as well as external customers and partners.

Jim's research background spans broad areas of computational mechanics, adaptive finite element methods, and V&V. He joined Sandia National Laboratories in 1997 as an architect of the SIERRA computational mechanics framework. From 2003-2007, he served as manager of the Advanced Computational Mechanics Department, where he helped lead the growth of SIERRA to support new customers, new HPC platforms, and an expansion of new multi-physics capabilities.

Education/Background

Jim holds B.S. and M.S. degrees in Mechanical Engineering from the University of Illinois at Urbana-Champaign, and a Ph.D. in Mechanical Engineering from Stanford University. His prior experience includes two years as Senior Engineer at Object Reservoir, Inc., in Austin, TX, and three years as Senior Structures Engineer at Planning Research Corporation in Hampton, VA (contracting to NASA Langley Research Center).

From 2010-2014, Jim served on the Executive Council of the U.S. Association for Computational Mechanics (USACM). He currently serves as Chair of the USACM Technical Thrust Area on Uncertainty Quantification and Probabilistic Analysis.
