About

My research interests are in the two principal areas of surfactant science and biomedical engineering. Using an interfacial polymerization process very similar to emulsion polymerization, we are modifying the surfaces of commercially important materials and also exploring the technique as a means of forming unusual polymers. Our efforts focus on learning the range of versatility of the method and on characterizing these thin polymer films. Other projects in the surface science group involve surfactant-based separations and the synthesis and study of novel surfactants. One of these is a double tail surfactant with a hydrocarbon chain and a fluorocarbon chain. We believe this extraordinary surfactant will form striated reverse, rod-like micellar aggregates which we have called "candy cane" micelles.

Within biomedical engineering, my students and I are interested in biotransport phenomena and particularly in biorheology. We are investigating thrombolysis or the dissolution of blood clots by plasminogen activators. In addition, damage to blood associated with the non-Physiolgic flow that occurs in some medical devices.
