Our mission is to develop novel sensor platforms, utilizing nano-structured semiconducting (organic/inorganic) materials. Our primary focus is on tuning their surface activity to achieve sensitive and selective detection of chemical species. Our research goals include designing novel active layers and catalysts. We are also interested in gaining fundamental understanding on sensing mechanisms. These objectives draw from multidisciplinary backgrounds in material science, chemistry, and chemical engineering. (See details in Research Interests)
