Research Interests/AreasEnergetics, kinetics and dynamics involved in formation/growth/reaction of low-dimensional functional materials and the materials’ novel properties studied using computational and experimental approaches. The theoretical and computational approaches adopted include optimization algorithms, molecular dynamics simulations and Monte Carlo methods, based on multi-level theories ranging from molecular mechanics, semiempirical theories, to first-principles theories. Recent research focus is on nanoscience, including interactions of nanomaterials with chemical, biological, and medical systems, aiming at promoting the applications of nanostructured materials in energy-related and chemical, biological, medical, and environmental areas. Developments of related theories and methodologies.
