Bethany A. Rudd

Assistant Professor of Chemistry


  • B.S., Ohio State University
  • Ph.D., Ohio State University


Bethany Rudd joined Ohio Wesleyan University in 2018. She received her undergraduate degree from Ohio State University, conducting undergraduate research in the theoretical chemistry group of Dr. Anne McCoy. She then received her Ph.D. in Physical Chemistry from Ohio State where she was a graduate student researcher in the Center for Aerosol Impacts on Chemistry of the Environment (CAICE), an NSF Center for Chemical Innovation, under the direction of Dr. Heather Allen.

Current research in the Rudd laboratory is focused on molecular organization at air-aqueous interfaces of biological and atmospheric relevance.
