  • Ph.D., Purdue University, 1980

Interests and Expertise

Our research is primarily interdisciplinary in nature, directed toward development of impedance-based electrical and wavefront-distortion based optical sensors for chemical, biochemical and materials applications. Current projects include organic synthesis of specialty monomers for functionalized polymers and self-assembled molecular monolayers on metal surfaces, investigation of microscopic interdigitated electrode arrays chips for impedance spectroscopy and application of Shack-Hartmann single beam interferometers to wavefront characterization of laser beams interacting with surface-modified polymers.
