Summary
👤
Senior🎓
Top SchoolIan Greenquist is an R&D Staff Nuclear Fuels Engineer with 10 years of experience advancing fuel performance modeling, multiphysics coupling, and experimental validation at Oak Ridge National Laboratory. He invented the patent-pending UO2-Liquid Metal Suspension (ULIMES) fuel concept and has led projects spanning uncertainty quantification, high-burnup and metallic fuels, and forensic taggant effects. Ian merges deep microstructural simulation expertise—contributing phase-field capabilities to the widely used MOOSE framework—with practical experimental and control-system analysis to raise fidelity in reactor safety studies. Known for reliability and continuous improvement, he couples strong coding skills in C++/Python and ML integration with a PhD-trained foundation in sintering and materials modeling. Based in Oak Ridge, he aims to make nuclear energy safer and more affordable by translating novel fuel ideas into validated, deployable technology.
