He is an expert in the development and application of atomistic/molecular simulations techniques and has extensive experience with molecular dynamics, kinetic Monte Carlo, and electronic structure simulations, including rare-event techniques. Dr. Kerisit has developed molecular dynamics and Monte Carlo computer codes including programs to simulate glass corrosion in aqueous conditions and charge transport in crystalline solids. Since joining PNNL in 2004, Dr. Kerisit has worked on a wide range of projects related to the chemistry of mineral-water interfaces, the interaction of radiation with crystalline solids, carbon capture and sequestration, the aqueous corrosion of nuclear waste glasses, the mechanisms of mineral nucleation and growth, and the redox properties of natural systems.
