Fonseca is Professor of Anthropology in the Department of Social Sciences at the Universidade Federal do Rio Grande dul Sul, and directs the doctoral program in social anthropology at the Universidad Nacional de San Martin. She began working in Brazil over 30 years ago, first studying class hierarchy in working class neighborhoods. Since then, her research has evolved to look at kinship practices, children and child circulation, childcare public policy, gender relations within families, and the intersection of law with science and technology in governing families. Dr Fonseca has published extensively in English and Portuguese. Her most recent English-language work includes “Global route or local detour? Following the path of DNA paternity tests in Brazil” (chapter in Globalization, Reproduction and the State. Duke University Press 2011). She is currently finishing a book project that examines the role of DNA technologies in paternity disputes.
