Biography

Generally interested in behavioral ecology and evolutionary biology, with an emphasis on sperm competition, urban ecology, mammalian reproductive physiology, and olfactory communication. Although I have mostly worked with many species of rodents, I have also studied primates, meerkats, birds, amphibians, and tardigrades.
