Our group’s current research efforts are largely devoted to the study of advanced electronic materials processing issues, particularly those related to thin film deposition (the group operates one Molecular Beam Epitaxy (MBE) and six chemical vapor deposition (CVD) systems. In one system we have coupled a Raman spectrometer to a CVD reactor, which can be x-y-z translated to measure gas phase composition and temperature profiles.…
My work has to do with the stability of phase boundaries as one phase displaces another. Of particular interest are electrodeposition, solidification, precipitation, and other related phenomena.

Our research projects are in three major areas: biomedical, surfactant solutions and advanced materials. In the biomedical area, we investigate surface chemical aspects of polymer adsorption on contact lenses in relation to biolubrication and comfort in the eyes. We also study transdermal diffusion of local anesthestics.
In various engineering processes such as cleaning, lubrication or dispersions, the adsorption of surfactants at the interface is very important.…
