RESEARCH INTERESTS


I am a broadly trained biological anthropologist whose research focuses on human variation in health and how evolutionarily novel factors shape human biology. Since 2007, I have conducted fieldwork in Amazonian Ecuador as research coordinator of the Shuar Health and Life History Project. The project focuses on a number of different dimensions of health, subsistence, economy, and demography among the Shuar forager-horticulturalists. Many Shuar, as is common in developing regions, are currently experiecing rapid integration into a market economy. My research documents the biological consequences of this transition while highlighting the ways in which local ecological conditions shape Shuar life history. My work has implications for the evolution of health and disease and allows for a better understanding of chronic disease risk in industrialized countries. Moreover, I am interested in the mechanisms that support the role that early developmental life plays in shaping adult health.
