The acronym LOST stands for Law, Organization, Science and Technology. Anthropology of Law (L), Organization Studies (O), and Science and Technology Studies (ST) are three vigorous transdisciplinary fields. A growing academic current mingles these fields and thereby engenders provocative insights. Working at the intersection of these fields and fusing their approaches, we additionally emphasize the ethical and aesthetic dimensions of fact-making in the contemporary. The ambition of our detailed ethnographies is to respond to long-standing questions raised in social theory and philosophy and vice-versa, to render those questions into ethnographic inquiries with a special focus on critique. We address issues of global and planetary scope, although several of our empirical projects are situated in Africa. Since its inception in 2002, LOST has expanded – from a small group localized in Halle to a decentralized network of independent scholars.
