Our lab studies animal communication and sexual selection from an integrative perspective that includes a wide range of behavioral ecological, neuroethological, developmental, genetic, and evolutionary approaches. Birds are our most common model system, but we also have worked with insects, spiders, shrimp, lobsters, lizards, and primates, including humans. The central question that drives our work is how information, in the broadest sense of that word, is used by organisms to maximize survival and reproductive success.
