Stephen Suomi is a primatologist. For several years, his laboratory at the National Institutes of Health has carried out a broad program of research with rhesus monkeys (Macaca mulatta), investigating biobehavioural development throughout the lifespan.

Three general themes have characterized this work: first, the role of specific genetic and environmental factors (and their interactions) in shaping individual developmental trajectories; second, the issue of developmental continuity versus change and the relative stability of individual differences throughout development; and third, the degree to which research findings from monkeys studied in captivity generalize not only to monkeys living in the wild but also to humans living in different cultures.
