Paul Fenter is the Director of the Center for Electrochemical Energy Science, a U.S. Department of Energy-funded Energy Frontier Research Center that seeks to understand the complex interfacial reactivity and reaction pathways in lithium-ion battery systems. He is also a Senior Physicist and Group Leader for Interfacial Processes in the Chemical Sciences and Engineering Division.

Dr. Fenter joined Argonne in 1997 after earning his PhD in Physics from the University of Pennsylvania and completing his postdoctoral studies at Princeton University. He has a BS in Physics from Rensselaer Polytechnic Institute (magna cum laude).

His research probes the structure and reactivity of solid-liquid interfaces through the use and development of novel synchrotron X-ray scattering, spectroscopy, and microscopy techniques at Argonne’s Advanced Photon Source.

Dr. Fenter is a Fellow of the American Physical Society and the winner of the 2012 Bertram E. Warren Diffraction Physics Award from the American Crystallographic Association. He is a member of the American Chemical Society, Materials Research Society, and Geochemical Society.
