Dr. Katherine Royston is an R&D staff member in the HPC Methods for Nuclear Applications Group at Oak Ridge National Laboratory. Dr. Royston’s research interests focus on the development and application of modeling and simulation techniques for radiation transport. She is experienced with working on large code systems in a high-performance computing environment. Dr. Royston has worked on numerous fusion neutronics analyses in support of the ITER fusion reactor, including shield design and shutdown dose rate calculations, as well as beamline analyses for the High Flux Isotope Reactor as part of the plutonium production effort. She is a developer for the Shift Monte Carlo code and in that role contributed to the DOE Energy Innovation Hub CASL (Consortium for Advance Simulation of Light Water Reactors) and the ExaSMR subproject of the Exascale Computing Project.
