A Certified Applied Animal Behaviorist,
Specializing in Animal Behavior and Statistics

My current academic interests revolve around applied animal behavior: dogs, cats, and non-human primates, and welfare, enrichment, and behavior modification methods. This work overlaps with my primary research interests which have, for many years, focused on complex social behavior in highly cognitive animals (primates, corvids, and cetaceans). This research, and my applied interests, have brought me to a new level of understanding of the importance of temperament in social behavior, whether in primates, corvids, killer whales, or dogs and cats.
