Summary
👤
Senior🎓
Top SchoolThomas Evans is a Distinguished R&D staff scientist with 14+ years at Oak Ridge National Laboratory and prior technical experience at Los Alamos, specializing in computational radiation transport across nuclear engineering, astrophysics, HEDP, and medical applications. He designs and implements large-scale deterministic and Monte Carlo transport codes for massively parallel systems, leading development of Denovo and Shift which are integrated into ORNL's SCALE and CASL/VERA toolchains. A prolific researcher with 88+ refereed publications, he leads DOE-funded efforts including CASL radiation transport and an Exascale Computing Project application for coupled Monte Carlo neutronics and fluid flow of SMRs. Thomas combines deep theory in stochastic/deterministic methods and preconditioning with practical software engineering for high-performance, coupled-physics simulation—an uncommon blend that powers mission-driven modeling at exascale.
