Biography

Dr. C. Scott Clem holds a bachelor's degree in Conservation Zoology (Auburn University), a master's degree in Entomology (Auburn University), and a PhD in Entomology (University of Illinois at Urbana-Champaign). He also did three years as a USDA NIFA postdoctoral fellow in entomology at the University of Georgia in Athens. He started his position at Illinois State University in fall of 2024.

Research Interests & Areas

I am a multidisciplinary research entomologist and ecologist with a spectrum of interests across basic and applied science. Topics I work on include insect migration, insect biodiversity and conservation, biological control, toxicology, faunistics, science outreach, and integrated pest and pollinator management (IPPM). I am especially interested in the biology and ecology of hover flies (Diptera: Syrphidae) and other beneficial insects.
