Elizabeth J. Biddinger


Elizabeth J. Biddinger joined the Department of Chemical Engineering at The City College of New York as an Assistant Professor in August of 2012.  Her research interests encompass green chemistry and energy concerns.  She has experience in catalysis, electrochemistry, alternative solvents, green chemistry and sustainable engineering.  Prior to joining City College, Prof. Biddinger was a Post-doctoral Fellow at the Georgia Institute of Technology studying alternative solvent systems for green chemistry and sustainable engineering applications, including CO2 capture, nanoparticle synthesis and homogeneous catalyst recycle.  She received her PhD in 2010 in Chemical Engineering from The Ohio State University and her BS in 2005 in Chemical Engineering from Ohio University.  Her research at Ohio State involved the development and investigation of nitrogen-containing carbon nanostructures as oxygen reduction electrocatalysts for PEM and direct methanol fuel cells.  In the past, she also worked on electrocatalysis development for the production of hydrogen by ammonia electrolysis.

Professor Biddinger has been recognized for her research with multiple awards since being at City College including the 2018 US Department of Energy Early Career Award for investigation of the kinetics and reaction mechanisms for biomass electroreduction, the 2016-2017 Electrochemical Society - Toyota Young Investigator Fellowship for studying switchable electrolytes for battery safety, and the 2014 CUNY Junior Faculty Research Award in Science and Engineering (JFRASE) sponsored by the Sloan Foundation to study CO2 electroreduction.

Professor Biddinger has held several leadership posts in professional societies including Director in the Catalysis and Reaction Engineering Division of the American Institute of Chemical Engineers (AIChE), member of the Publications Subcommittee of the Electrochemical Society (ECS), Student Awards Chair for the Industrial Electrochemistry & Electrochemical Engineering Division of ECS. In the past, she also served as chair and vice-chair of the Central Ohio Professional Section of American Institute of Chemical Engineers.

At City College, Professor Biddinger's research program focuses on the development of new electrocatalysis systems and the use of alternative solvents for applications in energy and green chemistry fields.
