Dimitris Xygalatas is Assistant Professor of Anthropology at the University of Connecticut and Associate Professor at the Interacting Minds Centre at Aarhus University.

Xygalatas has published numerous articles on ritual, cognition, and culture. His recent book, The Burning Saints, is a cogntive ethnography of the fire-walking tradition of the Anastenaria in Northern Greece.
