My research falls in with life history; the evolutionary study of the human life course. I focus on steroid hormones as a critical link between energetics, the brain and the timing of childhood growth, pubertal maturation, and senescence. My early work included fieldwork among Turkana and Ariaal pastoralists of northern Kenya, as well as school boys in Zimbabwe. I focused on the impact of ecological factors on hormones (mostly testosterone) on male puberty and aging. Since then, I have shifted my attention to adrenarche (the onset of adrenal DHEAS production) and its role in middle childhood, including a series of theoretical papers suggesting that the emergence of middle childhood is related to the impact of DHEAS on brain development in humans and the great apes. Most recently, I have begun to explore the development of adiposity among foraging population for what they can tell us about the evolution of energetic trade-offs in human growth and development. I have also supervised graduate students on topics ranging from primate growth, development & reproduction, to the understanding of evolution among museum patrons and college students, to chronic pain among global war on terrorism veterans.
