Dr. Evan Zucker, Professor of Psychology, studies the social and biological influences on the behavior and reproductive outcomes of nonhuman primates, as well as studying naturally-occurring patterns of human behavior (human ethology) and other aspects of social phenomena. His recent research has focused on the relationship between familial social status and life-history variables, as well as how indices of health in black howling monkeys are related to ecological factors, group composition factors, and reproductive status.
