Research Interests

My research interest focuses on nanoscale measurements of physical and mechanical properties of materials, as well as the development of biomimetic materials. Currently, I am working to refine and optimize a cantilever-beam based instrument for evaluating polymerization stress, and for simultaneous measurement of shrinkage and modulus evolution upon polymerization. We also aim to develop a better understanding of the polymerization process through these measurements.

My previous work includes:

 · Tribological properties (friction and wear) of polymers and polymeric nanocomposites at small length scales

 · Nanoindentation method for materials properties

 · Development of gecko-inspired smart adhesive (fabrication, experiments, and modeling)
