Our focus is on the properties of polymer surfaces and interfaces, with an emphasis on the adhesion of "soft materials." Examples range from traditional pressure-sensitive adhesives (sticky tape) to highly specialized polymeric gels commonly used in biomedical applications.

There is little understanding of the relationship in these systems between polymer adhesion and the structure of the interface on molecular or submolecular scale. We seek to make this connection through studies of well-characterized model systems synthesized in our own lab and through carefully designed fracture mechanics experiments.

Related problems of interest to us include polymer/inorganic composites and the origins of adhesion and mechanical response in biological systems.
