Bio

Seth Johnson specializes in high-performance computational particle transport as a senior R&D staff at Oak Ridge National Laboratory. Although his background is in nuclear engineering, with a B.S. from Texas A&M University and a Ph.D. from the University of Michigan, computational physics and scientific software ecosystems have been his passion for almost twenty years.

Over his career, Seth has developed new methods and tools in hybrid deterministic–Monte Carlo transport, computational geometry, sensitivity/uncertainty methods, high-fidelity fusion neutronics, inter-language code operability, high energy physics, and quantum computing. He is currently the lead developer of the Celeritas HEP simulation code.
