Prof. Han’s research interests focus on theory, modeling and simulations of materials. Principally he works on the thermodynamics and kinetics of defects in crystalline materials, such as point defects, dislocations and interfaces, and the implications on the mechanical properties of polycrystals. His research approach is multiscale, including molecular statics/dynamics, (kinetic) Monte Carlo, and continuum models.
