Summary of Research Activities

My research focus is to develop technologies to create, characterize, and apply biointerfaces to: generate biosensors for DNA, protein and cell detection; develop biomaterials for tissue regeneration and drug delivery; and develop enzyme immobilization schemes for improved activity in biofuel cells and other immobilized enzyme systems. Biosensors will enable rapid diagnostic screening of patients for pathogenic and genetic diseases, enable rapid, onsite food and water quality testing, and provide early warning of biowarfare agents in military and homeland defense. Understanding of biointerfaces is integral to the design of biomaterial substrates for eliciting responses from living systems for tissue regeneration, the integration of implantable devices and the control of drug delivery.
