Elliot Fratkin is an anthropologist who has spent much of his career studying nomadic pastoralists, particularly Ariaal (mixed Samburu/Rendille communities) in northern Kenya. Much of his work focuses on ecological adaptation and social change ("As Pastoralists Settle"). His most recent book "Laibon: An Anthropologist's Journey with Samburu Diviners of Kenya" recounts his early fieldwork and relationship with a family of Samburu medicine men, who introduce Fratkin to the world of sorcery and its prevention. Fratkin is a Professor of Anthropology at Smith College in Northampton Massachusetts; he is a US Fulbright Scholar in Ethiopia (2011-2012) and was a Fulbright Scholar in Eritrea in 2003. In addition to his work in East Africa, Fratkin has visited and studied pastoralists in Chad, Cameroon, and Mongolia.
