He is a computational scientist at Idaho National Laboratory specializing in parallel, nonlinear, fully coupled multiphysics software. His technical skills include numerical methods, high-performance computing, nonlinear solid mechanics, material model development, finite element contact, and multiphysics coupling. He joined INL in 2010 with a principal focus on nonlinear solid mechanics capability development. He is the primary author of BISON, INL’s nuclear fuel performance application. He now manages INL’s Fuel Modeling and Simulation Department, which develops a set of multiphysics applications in support of several U.S. Department of Energy’s nuclear energy programs. Before joining INL, he spent 9 years at Sandia National Laboratories and worked on the solid mechanics applications in SIERRA. He has a bachelor’s and master’s degrees in civil engineering from Brigham Young University and a doctorate in civil engineering from the University of Illinois at Urbana-Champaign.
