Research Interests

My research emphasizes on the cell biophysics. We are particularly interested in characterizing the cellular mechanical properties, motility, and adhesions, which have a great impact on the modern tissue engineering, cancer research, and neuroscience. As for the tools, we developed the AFM based microrheology in order to quantify the viscoelastic properties of the biological samples. This technique combined with the modern material engineering based on self-assembly and soft lithography allows us to develop the nano-structured polymer scaffold to investigate the cellular adhesions and motility. We also study the single molecule force spectroscopy using the AFM for the accurate characterization of the mechanical properties of such scaffolds. By incorporating the optical technique such as FRET we are able to detect the cellular events in the molecular scale with the real-time monitoring.
