Hadza Energetics, Ecology, and Health
With collaborators Brian Wood and David Raichlen, we are engaged in long term field work with the Hadza commuity, a hunting and gathering population in northern Tanzania. Our work focuses on the relationships between diet, physical activity, energy expenditure, and health over the life course.
Daasanach Health and Life History Project
We aim to investigate the effects of lifestyle change on early childhood growth among the Daasanach, a population of semi-nomadic pastoralists living in remote northern Kenya. We further seek to understand the tradeoffs between growth and other competing energy demands (i.e. physical activity and immune function) in a population transitioning towards a more sedentary and market integrated way of life. https://sites.duke.edu/pontzerlab/daasanach-heath-life-history-project/

Lemur Reproductive Energetics Study
We are investigating differences in energy expenditure and physical activity over the course of pregnancy and lactation in Ruffed and Ring-tailed lemurs, primate species that differ in maternal behavior and life history traits.
Maternal Metabolic Limits during Pregnancy and Postpartum
We are testing the maternal metabolic limits hypotheses and investigating the effects of daily physical activity on maternal energy needs and pregnancy outcomes.
