Elizabeth J. Biddinger joined the Department of Chemical Engineering at 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, Dr. 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.

At Ohio State, she received multiple awards including the Council of Chemical Research (CCR) Award to participate in the annual CCR meeting, the 2009-2010 Dow Fellowship, the Ohio State University Fellow Award, the Department of Chemical and Biomolecular Outstanding Teaching Associate Award, and travel awards to the North American Catalysis Society National Meeting and the American Institute of Chemical Engineering National Meeting.

Professor Biddinger has held several leadership posts in the past including chair and vice-chair of the Central Ohio Professional Section of American Institute of Chemical Engineers, member of the Atlanta Professional Section of the Society of Women Engineers Outreach Programming Committee, Academic Officer of the Chemical Engineering Graduate Council at Ohio State and as the Ohio University Manasseh Cutler Scholars Class of 2005 Class Agent.

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.
