General Research Interests

Our research is broadly focused in the areas of analytical chemistry, electrochemistry, electroanalytical chemistry, surface chemistry, and bioanalytical chemistry. A variety of electrochemical techniques, including scanning electrochemical microscopy (SECM), electrogenerated chemiluminescence (ECL), electrochemical quartz crystal microbalance (EQCM) and electrochemical impedance spectroscopy (EIS), together with several other analytical and physical methods, such as UV-visible spectroscopy, fluorescence, scanning electron microscopy (SEM), transmission electron microscopy (TEM), and electron paramagnetic resonance spectroscopy (EPR), are applied to the study of chemical and biological problems.
