  • atomistic modeling and simulation study of structural, dynamical and electronic properties as well as phase transformation of condensed matter systems and molecules, including:
    • liquid and amorphous materials
    • defects
    • surfaces
    • clusters
    • biological molecules
  • develop genetic algorithm for global structure optimization and Gutzwiller density functional theory and computational code for studying ground state energy and properties of strongly correlated electron systems
  • ab initio calculation and tight-binding molecular dynamics simulation studies of formations, structures, and stabilities of surface-based nanostructures
