My research falls in the general area of life history; the evolutionary study of the human life course. I focus on the way in which steroid hormones form a critical link between energetics and the timing of important life events including childhood growth, pubertal maturation, and senescence. My doctoral work with Richard Udry on the role of testosterone on adolescent development and sexual behavior, included a comparative project in Zimbabwe. Subsequent fieldwork, funded by the NSF and Wenner-Gren, focused on the impact of nutrition on adolescent development, male reproduction and aging among Turkana, and Ariaal pastoralists of northern Kenya. More recently, I have focused on the role of DHEAS in human brain development and aging. Recently, I hypothesized that DHEAS represents a critical link between increased meat consumption and the energetics of human brain development in the course of human evolution. I plan to use data collected among the Ju’Hoansi of Nyae Nyae for an initial test of the importance of animal protein and fat reserves in the timing of adrenarche. In addition to upper human biology courses, I also teach introductory level Human Evolution and Variation, and a course on Indigenous Religion. I have supervised graduate students on a number of different topics, including primate growth, development and reproduction, and the understanding of evolution among college students.
