Robert J. Messinger is an Associate Professor and Director of Graduate Studies in the Department of Chemical Engineering at The City College of New York (CCNY). He earned a B.S. in chemical engineering from The Ohio State University (2006) and a Ph.D. in chemical engineering from the University of California, Santa Barbara (2012). Afterwards, he studied physical chemistry and electrochemistry at the CNRS, France, first as a European Union Marie Curie Postdoctoral Fellow in Orléans (2012-2014) and then jointly with the CNRS and Grenoble Institute of Technology (2014-2015).

At CCNY, his research team studies electrochemical materials, chemistries, and processes aimed at solving societal challenges in energy and the environment, particularly in energy storage and recycling. He is an expert in nuclear magnetic resonance (NMR) spectroscopy. Prof. Messinger won an NSF CAREER award (2019) and is the Founding Director of the NASA-CCNY Center for Advanced Batteries for Space.
