Research interests include basic and applied research on hydrodynamic electroanalytical techniques in liquid chromatography and capillary electrophoresis, adsorption phenomena at noble metal electrodes, and advanced sample preparation techniques. A major thrust is to further understand and expand the limits of pulsed electrochemical detection (PED) techniques. Bioanalytical problems of critical significance lie in the areas of pharmaceutical, toxicological, forensic, environmental, pharmaceutical, and life science arenas.
