My research interests lie at the intersection of psychology and biology, including the psychological and physiological processes that are conserved across cultures and species. My work falls into the general area of behavior analysis, comparative psychology and ethology. I am also interested in computational approaches to model behavior. I have worked with a wide range of species, from honey bees to horses, in homes, farms, zoos, and the wild. I am fond of many species and topics, including the behavioral ecology of amphibians and reptiles, and the social behavior of birds. Most recently, I have become interested in tropical cockroaches and other invertebrate models of behavior.
