Daniel Esposito received his Ph.D. in Chemical Engineering at the University of Delaware and studied as a postdoctoral research associate at the National Institute of Standards and Technology (NIST) under a National Research Council fellowship. He is now an Associate Professor in Chemical Engineering at Columbia University, where he is also a core member of the Columbia Electrochemical Energy Center (CEEC). His group’s research interests relate broadly to the development of electrochemical technologies for clean energy applications. Specific topics of interest include electrocatalysis, photoelectrochemistry/solar fuels, membraneless electrochemical cells, and the use of in situ analytical techniques to study the performance and properties of (photo)electrocatalytic materials at high spatial resolution. Esposito was named a 2017 Scialog Fellow in Advanced Energy Storage and received an NSF CAREER to study electrochemical reactions at buried interfaces.
