Although my lab is closed, I do collaborate with colleagues at UT and around the world. Our research group has, over the years, worked on numerous topics that include field and laboratory studies using observational, experimental, and molecular genetics approaches to questions of ontogeny and chemoreception in reptiles, as well as communication, predation, social behavior, cognition, phylogeny, mating, and antipredator behavior. Snakes were a primary focus because of our interest in the tongue-vomeronasal organ system, however, turtles, crocodylians, and lizards (especially iguanas and monitors) were also studied. Black bear behavior and development has been another important and continuing interest.  A major interest for over 50 years has been play behavior, its origins, mechanisms, ontogeny, and evolution, especially in “non-playing” taxa.

I also have a continuing interest in the ethical treatment of animals, and theoretical and historical issues in ontogeny, play, anthropomorphism, ritual, and religion as well as the historical antecedents of contemporary ethology, psychology, and behavioral ecology. I also have edited several journals and am the Founding (and current) Field Chief Editor of Frontiers in Ethology https://www.frontiersin.org/journals/ethology
