We are an electrochemistry group at the University of Washington. We work on interesting problems in both fundamental electrochemistry and electroanalytical (bio)sensors. We develop and use powerful analytical and physical chemistry tools (e.g., optical microscopy, microfabricated nanoelectrodes, nanopores etc.) to study chemical reactions at the electrochemical interface.
