Alexandra Brewis studies how stigma and other forms of social exclusion shape human biology, with a special focus on the health challenges of obesity and climate change. Her books include Obesity: Cultural and Biocultural Perspectives. She received her Ph.D. in anthropology from the University of Arizona and now serves as the director of the School of Human Evolution and Social Change at Arizona State University (ASU), where she is also a president’s professor. To leverage social science research in advancing workable and sustainable solutions to local community-identified health challenges, Brewis co-leads the Mayo Clinic–ASU Obesity Solutions initiative. She blogs about stigma (with Amber Wutich) at lazycrazydisgusting.com.
