Our research interests are in the emerging field of nanoelectrochemistry. We employ nanometer-sized electrochemical probes for molecular level characterization of chemical processes and materials. A wide variety of systems and processes are studied including charge-transfer reactions at metal/solution, liquid/liquid and semiconductor interfaces, nucleation/growth of metals, bioelectrochemistry, transport processes in nanoconfined spaces, and electrocatalysis. The main focus is on obtaining quantitative physico-chemical information by combination of experiments with mathematical modeling and computer simulations.
