In our lab we investigate the fundamental questions of life history theory: How do organisms allocate resources to the competing demands of growth, reproduction, and somatic maintenance? How do organisms use cues in their environments to predict future demands? How do early environments affect health and well-being later in life? How does our modern environment differ from the conditions under which we evolved, and what are the consequences of our novel environment on health and ontogeny?

We focus on both field and laboratory work to examine human biology and behavior in ecological context. In the lab we measure hormones, white blood cells, and other biomarkers to characterize stress responses and life history allocations. In the field we study pathogen exposure, social structure, stress, and lifestyle change through market integration and globalization.
