Biography:
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 joined INL in 2010 with a principal focus on non-linear solid mechanics capability development. He is the primary author of BISON, INL’s nuclear fuel performance application. Dr. Hales now manages INL’s Fuel Modeling and Simulation Department, which develops a set of multi-physics applications in support of several DOE-NE programs. 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.
