Research Description

His professional interests are atomistic description and evolution of nuclear fuel and structural materials. He has extensive experience on interatomic potential development, particularly related to uranium and uranium-alloys. He has studied a number of phenomena in nuclear materials including radiation damage, effects of strain on point defects, diffusion, free surface and grain boundary properties, fission gas bubbles, thermal transport and optical properties. His research has primarily utilized density functional theory, molecular dynamics and phase-field methods.
