Research Interests


I am a postdoc at Carleton University. My research interests span evolutionary and behavioral ecology. I study the process of adaptation, focusing on traits that prey species evolve to avoid predators. The paradigm that I have investigated most is mimicry, where one organism evolves a resemblance to another because of the selective benefits of sharing an appearance to mutual predators. I am interested in why mimicry is often imperfect, how mimicry arises from non-mimetic phenotypes, and how mimetic phenotypes are produced on a proximate level. These questions often entail studying the cognitive and perceptual systems of predators as well. I use field experiments, mathematical models, and a little wet lab work to address these issues.
