Gregg Mitman is the Vilas Research and William Coleman Professor of History of Science, Medical History, and Environmental Studies at the University of Wisconsin-Madison. His research and teaching interests span the history of science, medicine, and the environment in the United States and the world, and reflect a commitment to environmental and social justice. Together with Sarita Siegel, he recently directed and produced  In the Shadow of Ebola, a short film available online on PBS/Independent Lens that offers an intimate portrait of a family and a nation torn apart by the Ebola outbreak in West Africa. Siegel and Mitman have also just completed a one-hour documentary, The Land Beneath Our Feet, which weaves together rare motion picture footage shot on the Harvard expedition with the journey of a young Liberian man seeking to understand how the past has shaped land rights issues in Liberia today. Website. Contact.
