Biography

Kevin Judge completed his B.Sc. and M.Sc. at the University of Guelph and then a PhD at the University of Toronto Mississauga. After working on the mating system of the bullfrog (Lithobates catesbeianus) in Algonquin Provincial Park in Ontario for his M.Sc., Kevin made the switch to working on sexual selection, or competition over mates, in the fall field cricket (Gryllus pennsylvanicus) for his PhD dissertation. He followed that up with a postdoctoral fellowship at the University of Lethbridge working on the evolution of aggressive behaviour and weaponry in North American field crickets. 

His current research interests involve the study of sexual selection in a group of sexually-cannibalistic insects (genus Cyphoderris) and how that competition selects for a range of diverse behaviours and morphologies, as well as the interaction between ecology and mating system. Kevin’s teaching interests closely mirror his research experience, and he teaches a fourth year course in entomology (BIOL 425: Introductory Entomology) and a first year course in introductory biology (BIOL 108: Organisms in Their Environment).

Available to supervise senior students' independent study.
