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.
