Erik Hannerz is a sociologist interested in subcultural authenticity. He earned a Ph.D. in Sociology from Uppsala University. In his PhD thesis Performing Punk he investigates the ordering and structuring of style and behavior among punks in Sweden and Indonesia, pointing to how the subcultural centers on plural definitions of both what punk should be and what it should be against. The thesis was reworked and published by Palgrave in 2015. Hannerz is a faculty fellow at the Center for Cultural Sociology, Yale University.
