I started my academic career as Associate Professor of Chemistry and member of the Laboratory for Surface Science and Technology (LASST) in the summer of 1998 after spending 12 years in industry at the Xerox Research Centre of Canada and Bomem Inc. [More History]

My research interests fall under the general umbrella of developing new material properties through the use of surface chemistry. Work is centered on the development and use of infrared and Raman spectroscopic techniques to probe reactions at the solid/liquid and solid/gas interface. The goal is to obtain an understanding of the relationship between the molecular surface chemistry and macroscopic properties of materials.

Although my industrial research has been targeted at imaging technologies (xerography, ink jet), it has spanned several surface chemistries such as, small molecule adsorption on high surface metal oxides, polymer and surfactant/polyelectrolyte adsorption on colloidal particles/pigments, surface reactions in supercritical fluids, and interfacial phenomena in optoelectronic thin organic film devices.

This activity has led to over 80 published articles and 14 US patents. I have been an invited speaker at several international/Gordon conferences and universities.
