Specifically I am interested in dispersions and emulsions of these materials. The stability of these colloidal systems is also critical. We are interested in studying novel materials and dispersants. A large part of this effort involves the study of polymers, surfactants and polymeric surfactants. We study the adsorption of these surface active materials as well as the stability of the dispersions and emulsions of the photographic active materials. We are also researching novel materials for use in new imaging systems. The rheology of these dispersions and emulsions is also of interest. We often have challenging problems with shear-induced flocculation, and well as other classical dispersion and dispersion stability problems.

Interests include: reading, writing, and working with young people.
