Yidong Gong is an Assistant Professor of Anthropology at New College of Florida, a public liberal arts college in the United States with a distinctive academic program that emphasises individualised learning. He studies how medical expertise and ethics influence biopolitics in transnational health care, and particularly their convergence and friction in Africa. His current book project examines China’s longstanding medical programs in South Sudan, which offer an alternative to the prevailing values of medical humanitarianism in regions marked by crisis or conflict.
