My work focuses on the evolutionary genetics of sexual selection (the outcome of mate choice and competition over mates). With collaborators, I have conducted experiments estimating costs and benefits of sexual selection in Drosophila melanogaster - a species with magnificent courtship behavior and ornamentation as well as cryptic aggression - and have proposed a general hypothesis for the evolution of courtship via genes that act in a sexually antagonistic manner (good for one sex but at the expense of the other; see, chase-away). Specifically, males sometimes appear to exploit female sensory systems in a way that is analogous to manipulative advertising (e.g., through increased volume or vivid coloration). Current interests center on evaluating the chase-away hypothesis through experimentation and literature analysis. Students are welcome to inquire about research opportunities.
