Dr. Luke Sinwell, a trained anthropologist, spends a significant amount of time writing and editing books about grassroots militants, but believes that he is at his best while standing by their side in a common struggle for social and economic justice. Luke's most recent engaged research project was centred around the long-lasting relationships that he and his fieldworkers built with trade unionists during the longest strike in South African mining history. This culminated in an ethnography called, "The Spirit of Marikana: The Rise of Insurgent Trade Unionism in South Africa" (Pluto Press: 2016). He is currently a Senior Researcher at the Centre for Social Change, University of Johannesburg.
