Broadly speaking I am a comparative psychologist. To be more specific, as an undergraduate and a masters student I studied habituation and dishabituation in sea anemones and taste aversion in leopard sharks. I originally intended to study learning in invertebrates for my PhD, but found myself studying personality in chimpanzees instead. Since then I have devoted my research career to the study of individual differences in personality, well-being, and intelligence in nonhuman primates and sometimes humans and other animals, too. I still remain interested in the study of animal learning and preparedness nor for classical ethology and behavioral ecology.
