Nanoscaled materials such as nanotubes, nanowires, nanoclusters, nanocomposites, and biological systems present unique properties on structures, mechanics, thermodynamics, and transports. The understanding of nanoscaled materials at atomic level is crucial for many phenomena. I currently work on following subjects, through theoretical analysis, modeling and simulation methods (such as molecular dynamics, tight binding and density functional theory):
