Our research focus is broadly divided into several areas. The first is focused on developing a fundamental understanding of the structure and dynamics of molecules at surfaces and interfaces using infrared-visible sum-frequency-generation spectroscopy (SFG) techniques. The goal of this research is to couple SFG and mechanics to directly relate macroscopic properties such as adhesion and friction with the structure and dynamics of interfacial molecules. Second, we build on the fundamental concepts of surfaces and interfaces to design new materials inspired by nature. As part of the integrated bioscience program and in close collaboration with faculty members in the IB program, we work with live animals, such as geckos and spiders, to understand natural materials. In addition, we provide fundamental knowledge and technological innovations in the areas of energy, environment-friendly materials, and nanotechnology.
