Jason Hales is a computational scientist specializing in parallel, nonlinear, fully coupled multi-physics software. His technical skills include numerical methods, high performance computing, non-linear solid mechanics, material model development, finite element contact, and multi-physics coupling. Dr. Hales currently serves as a senior advisor in the Advanced Scientific Computing Division. He joined INL in 2010 with a principal focus on non-linear solid mechanics capability development. Since joining INL, he has been a primary author of Bison, INL’s nuclear fuel performance application. Dr. Hales managed INL’s Computational Mechanics and Materials Department, which develops a set of multi-physics applications in support of several DOE-NE programs, from May 2014 to May 2024. Dr. Hales served in leadership positions in DOE-NE​ programs (Nuclear Energy Advanced Modeling and Simulation (NEAMS) and Consortium for Advanced Simulation of LWRs (CASL)) for six years. In those positions, he oversaw work on the development of models for novel nuclear fuels and materials. He has authored technical papers on computational aspects of mechanics and nuclear fuel behavior in journals such as Computational Mechanics and Journal of Nuclear Materials. Before joining INL he spent nine years at Sandia National Laboratories where he worked on the solid mechanics applications in SIERRA. Dr. Hales holds B.S. and M.S. degrees in civil engineering from Brigham Young University and a Ph.D. in civil engineering from the University of Illinois at Urbana-Champaign.
