Research Mission

The overall research program of the Water and Health Lab is designed to understand cross-cultural variation in how humans meet their water needs across distinct ecological contexts and how this relates to both acute and long-term health, hydration status, nutritional status, stress, and disease risk. Our research examines how humans respond behaviorally and physiologically to varying degrees of water access and insecurity, nutritional and epidemiological transitions, changing environments and resources availability, and shifting socioeconomic circumstances. In particular, these issues are explored in the Bolivian Amazon among indigenous Tsimane’ forager-horticulturalists, in Kenya among Daasanach agro-pastoralists, and in the United States using complex survey data from the National Health and Nutrition Examination Surveys (NHANES) and field based projects.

The Water and Health Lab integrates quantitative and qualitative data and research methods from the fields of biology, biological and biocultural anthropology, epidemiology, nutritional sciences, and environmental health to explore the relationships among hydration strategies, hydration status, nutrition, health and diseases in these populations. Additionally, the lab is part of a cross-disciplinary consortium aimed at assessing household water insecurity cross-culturally: the Household Water Insecurity Experiences Scale (HWISE) consortium.

Current Projects
