Physical Electrochemistry and In situ Spectroscopy

The physicochemical properties of electrode materials and particularly their reactivity toward specific electron-transfer processes, can be markedly modified by the presence of adsorbed species such as ions, molecules, or metals, even at sub- monolayer coverage. A basic understanding of the way in which these factors alter the electrochemical behavior is of both scientific and technological importance. Research interests include electrocatalysis and energy storage, with emphasis on in situ and ex situ spectroscopic techniques including UV-visible and Raman spectroscopies, electroreflectance, LEED-Auger-XPS and UHV FTIR, x-ray absorption fine structure, scanning probe microscopies and second harmonic generation.
