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.
