HUMAN EVOLUTIONARY BIOLOGY & HEALTH LAB

 

 

 

The Urlacher Lab @ Baylor University

We investigate the evolved bio-energetic pathways that drive variation in human development, metabolism & health

Our biocultural approach integrates field and laboratory methods spanning several disciplines. We develop new models and methods, test hypotheses, and strive to reduce health disparities.

Our research lies at the intersection of the fields of human biology, behavioral ecology, evolutionary medicine, and global health. We are particularly interested in how children adaptively allocate calories to competing physiological tasks (e.g., growth, immune activity, brain development) and the impact of early adversity on lifetime metabolic disease risk.
