Chair of the Anthropology Department and Director of the Visual Anthropology Program at San Francisco State University, Peter Biella is past president of the Society for Visual Anthropology and occasional editor of Visual Anthropology Review. His Yanomamo Interactive: The Ax Fight on CD-ROM made a significant contribution to interactive ethnography. Biella has produced films in the United States, Egypt, Costa Rica, Peru, Romania and Haiti. His most recent films, however, are collaborations with Tanzanian Maasai. Using a Freirian approach in the production of ‘trigger films,’ his Maasai Migrants Series stimulates shared learning about HIV and migration through post-screening discussions led by a Maasai facilitator. Award winning films include Art in Ayacucho and AIDS in the Barrio: Eso no me pasa a mi.
