Our research involves broad-based investigations of primate biological and behavioral development through comparative longitudinal studies of rhesus monkeys and other primates. Our primary goals are to characterize distinctive biobehavioral phenotypes in our rhesus monkey colony, to determine how genetic and environmental factors interact to shape the developmental trajectories of each phenotype, and to assess the long-term behavioral and biological consequences for monkeys from various genetic backgrounds when they are reared in different physical and social environments. A second major program of research investigates how rhesus monkeys and other non-human primate species born and raised under different laboratory conditions adapt to placement into environments that model specific features of their natural habitat.
