Summary
👤
Senior🎓
Top SchoolSteven Hamilton is a Group Leader and senior R&D staff scientist at Oak Ridge National Laboratory with 13 years of experience developing high-performance radiation transport and multiphysics software for reactor physics, shielding, and national security. He led the effort to port the Shift Monte Carlo neutron transport solver to GPUs and has run code on ORNL machines from Jaguar to Frontier, giving him rare hands-on expertise with successive generations of flagship supercomputers. His work spans Monte Carlo and deterministic methods, eigenvalue solvers, multiphysics coupling, and linear-solver preconditioning, with practical impact on advanced reactor and fusion neutronics projects. Trained with a PhD in Computational Mathematics and an MS/BS in Nuclear Engineering, he combines deep numerical methods knowledge with production-scale HPC engineering. An underappreciated strength is his knack for building custom tools and workflows when standard approaches fail, enabling solutions to unusually challenging simulation problems.
