My current research interest comprises various topics of polymer physics, including the dynamics of polymer under nano-confinement, wetting properties of polymer films on solid and liquid surfaces, and dynamics, phase behaviors and applications of polymer nano-composites. In addition, my work frequently involves the use of atomic force microscopy (AFM). Therefore, I am also interested in nano-mechanics, nanotribology and development of characterization techniques involving AFM.
