Dr. Carroll is an Assistant Professor of American Indian Studies at the University of Minnesota-Twin Cities. In 2003 Dr. Carroll earned a B.A. in Anthropology from the University of Arizona, and earned his PhD in Environmental Science, Policy, and Management from the University of California-Berkeley in 2011.
