About

Samuel Urlacher studies global variation in childhood development and the early life origins of metabolic health disparities from an evolutionary and bioenergetic perspective.

His work in the lab and in the field (primarily in Ecuador and Papua New Guinea) draws from many disciplines, including evolutionary biology, anthropology, immunology, nutrition science, psychology, economics, and epidemiology. He is particularly interested in how children allocate calories to competing physiological tasks (e.g., brain development, immune activity, and growth) and the impact of early adversity on lifetime metabolic disease risk (e.g., obesity and chronic inflammation). Much of his current work uses stable isotope-tracking methods to investigate the changes in children’s energy expenditure that may underlie the global nutrition/epidemiologic transition. An important goal of this work is to apply research findings to improve health outcomes.
