My interests lie in human health and reproduction, reproductive decision making, and evolutionary ecology. In particular I examine costs and trade-offs associated with investments in reproduction. I do this with a combination of quantitative and qualitative methods, including anthropometrics, demography, endocrinology, actigraphy, validated health surveys, dyadic peer ratings, alongside semi-structured demographic interviews and measures of social norms. My work is informed by a mix of evolutionary and behavioral ecology, cultural evolutionary theory, and evolutionary psychology, especially they relate to reproductive concerns. I am also a co-director of the Kunene Rural Health and Demography Project, a contributor to the ENDOW project, and a collaborator on the Shodagor Longitudinal Health and Demography Project.
