Elizabeth J. Biddinger is an Associate Professor in Chemical Engineering at T��ɫ��Ƶ.  Her research interests encompass green chemistry and energy concerns.  She has expertise in catalysis, electrochemistry, alternative solvents, green chemistry and sustainable engineering. In particular, she is interested in the electrification of chemical processes that transform wastes or renewable resources into valuable materials, chemicals and fuels for decarbonization and sustainability; and the use of ionic liquids and alternative solvents in electrochemical systems for improved performance and safety. Current research projects in her group include developing strategies for decarbonizing the chemical industry using renewable electricity (Sloan Foundation), understanding the reaction mechanisms and kinetics for the electroreduction of biomass-derived furanics (DOE), storing and releasing hydrogen from liquid organic hydrogen carriers (LOHCs) electrochemically (DOE & NSF), utilization of ionic liquids as electrolyte additives in CO₂ electroreduction (NSF), investigation of ionic liquid mixtures for batteries used in space applications (NASA), and recovery of critical materials from waste-to-energy ash using ionic liquids and electrochemistry (ARPA-E).

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), Secretary/Treasurer and 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. She is also an Associate Editor of ACS Sustainable Chemistry & Engineering.

Prior to joining City College in August 2012, 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
