Marcel Streng received his PhD in 2014 from the University of Bielefeld, where he worked in the DFG (German Research Foundation)-funded Special Research Field "The Political as Communicative Space in History". His thesis, entitled "Subsistenzpolitik im Übergang: Die Ordnung des Brot- und Fleischmarktes in Frankreich, 1846-1914“ ("The Politics of Subsistence in Transition: The Organisation of Bread and Meat Markets in France, 1846-1914"), has recently been published. In 2011 and 2012, he taught courses on the sociology of sports and violence as a lecturer at the University of Applied Sciences in Düsseldorf. Through 2009 and 2010 he worked at the Center for Interdisciplinary Francophone Studies at the University of Cologne. His main research areas are the history of the body, the history of violence, and economic and social history. He has published on the history of hunger strikes in German prisons, on the reform of the West German prison system during the 1970s, and on the body history of combat sports and self-defence (1920s to 1970s). Working also as a scientific translator from French and English to German, he has translated monographs and articles on the German welfare state, politics of "Heimat" in the GDR, and on the concentration camp of Buchenwald. His current research project focuses on processes of therapeutisation, health care and the inmates’ bodies in German prisons as well as on probation and rehabilitation since the late 1960s.
