Valerie Hänsch is Lecturer at the Department of Social and Cultural Anthropology, LMU Munich, Germany. In her work, she explores large infrastructures, technologies and politics of uncertainty, socio-environmental transformations and displacement in the Sudan. She is interested in the links between activism, engaged anthropology and visual culture. As a visual anthropologist, she uses the video camera both as a research tool and for the collaborative production of ethnographic films. Her films deal with dam-induced displacements, the modification of the Bedford lorry and rituals during Ramadan.
