We specialize in the development and application of linear and nonlinear optical techniques to study thin films and interfaces. This research is central to many advanced technologies in which boundaries play a crucial role, such as enhancing catalysis, preventing corrosion, optimizing the performance of electronic and photovoltaic devices, and improving lubrication.

In our most recent research we are studying interfaces in "soft" condensed matter systems. This includes single layers of flexible organic molecules and boundaries between dissimilar polymers. These investigations are motivated by widespread interest in photonic devices involving organic materials, and a need for fundamental understanding of adhesion.
