Laid the empirical and conceptual foundations of the field of human reproductive ecology, linking environmental factors to reproductive success, a crucial connection for investigating evolution and adaptation. This led to influential work on interactions between hormones and social relationships. Continuing extensive fieldwork in areas as diverse as Zaire, Argentina, The Gambia and the United States, his research on the health consequences of reproductive responses to lifestyle and environmental conditions is stimulating new insights and discoveries in evolutionary medicine.
