Professor Nicholas Blurton-Jones is professor of Psychological Studies in Education and has a joint appointment in Psychiatry and Anthropology. He received his Ph.D. from University of Oxford and was a Fulbright Psychiatry Scholar at the John Hopkins University Medical School. His research has included longitudinal and cross-cultural studies of parent-child interaction, with special attention to the child's contribution to the relationship and the need for better evidence before we assume effects of parents. Recurrent theme has been application of methods and frameworks from Biology in studies of human behavior. His current research includes behavioral ecology of foraging peoples: subsistence, children's work, reproductive strategies, and wherever the paradigm leads us into understanding evolution of the human life history, and into more complex aspects of social life.
