Dr. Leif Deyrup
Assistant Professor of Biology

L. Deyrup

Dr. Leif D. Deyrup graduated from Stetson University with a B.S. in biology and psychology in 2001, and a PhD in Entomology from the University of Georgia in 2005. While graduate teaching, he won both the Departmental graduate teaching award and an award for teaching excellence from the UGA Graduate School. He also won the Sigma Xi outstanding dissertation for his PhD work. After graduating, he was the Medical Entomologist for the state of Maine for two years and then moved into teaching for the University of the Cumberlands in 2008.

Most of Dr. Deyrup’s research has been in the evolution of behavior, physiological behavior and the biology of wasps. His current work is focused on behavioral ecology, evolution, community ecology and local invertebrate fauna. His research interests provide many opportunities for undergraduate students. In addition, he currently conducts research at the Archbold Biological Station, research institution with a special mission to study an endangered habitat called Florida scrub.
