From left: Hongfang, Andy, Bo, Sam, Rui, Yuting, Emily, Ruixuan, Milo, Peter, Rubin, Chris, Zhuoyu We are an electrochemistry group working on exciting 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 probe and understand the physical and chemical behavior of single molecules and nanoparticles at the solid/liquid, gas/liquid, and liquid/liquid interfaces.
