I originally became interested in anthropology as an undergraduate when I discovered that the discipline would afford me a unique opportunity to merge my interests in the social and biological sciences. Hence my approach to anthropological questions is distinctly biocultural – I am interested in how biology affects culture, how culturally patterned behavior affects biology, and how these forces interact over time. I make extensive use of an evolutionary perspective in both my research and teaching, which means that I consider how biology and behavior can be considered adaptive. I apply this approach to problems related to health, disease, demography, diet and nutrition, and human social behavior. My two main areas of research are in reproductive health and diet and nutrition.
