Gregory S. Tschumper obtained a B.S. from Winona State University in 1995 and a Ph.D. from the University of Georgia in 1999.
Tschumper was a Postdoctoral Fellow at ETH Zürich in Switzerland from 1999 to 2000 and at Emory University from 2000 to 2001. He then joined the University of Mississippi as an Assistant Professor in 2001, becoming an Associate Professor in 2007 and a full Professor in 2013. He served as Chair of the University of Mississippi Department of Chemistry & Biochemistry from 2016 to 2023.
Tschumper's research interests include physical chemistry, theoretical chemistry, computational chemistry, non-covalent interactions, hydrogen bonding, and van der Waals forces. His research group focuses on obtaining insights into chemical problems, particularly in biological, and organic chemistry through theory and computation rather than experimentation.
