Biographical Information

Research Interests

Research projects in the Locklin group are centered on the investigation and development of novel materials and methods for the precise control of organic molecular assemblies, both in solution and on surfaces as ultrathin films.  Our research activities involve organic and polymer synthesis, surface sensitive characterization techniques, nano- and micropatterning, and materials and device characterization.  The approach we take is multidisciplinary, which involves chemistry, physics, materials science, and chemical engineering. The devices of interest currently are enzymatic biofuel cells, smart polymer actuators, hybrid organic photovoltaic cells, and chemical and biological sensors. These devices are used as tools to investigate fundamental interfacial phenomena and to obtain a better understanding of inter- and intramolecular interactions that govern thin film architecture.  They are also of practical interest for nano- and microscale electronics, low cost and large area flexible plastic circuits, displays and disposable sensors.
