I am a human behavioral ecologist interested in understanding the adaptive nature of behavior as a function of local socioecological context.

My research focuses on a variety of questions related to reproductive decision-making and parental investment, and on understanding the social environment as a critical influence on how people negotiate life history trade-offs.

My current research focuses on male and female reproductive strategies both inside and outside of marriage, parental investment strategies of mothers and fathers, and the role of the mother-adult daughter relationship within the larger system of cooperative breeding.  I currently conduct fieldwork with the Himba, a semi-nomadic pastoralist group in Namibia. Previously, I worked in Australia with Martu Aborigines, looking at parental investment and the effects of demography on social support, as well as some work on diet in a mixed economy.
