is currently a lecturer in the Center for Latin American Studies at the University of Arizona, has a PhD in political science from the University of Hawaii. Before moving to Arizona she taught for fifteen years at Yale University, where she had joint appointments in the Department of Political Science, the School of Forestry and Environmental Studies, and the School of Public Health. She also taught for nine years in the School of Public Health at the University of Michigan, and was a Fulbright scholar for a year in Brazil at the Instituto de Saúde Coletiva, Universidade Federal da Bahia.
Her earlier work on public health politics morphed into an interest in environmental health politics and from there to an interest in the environmental movement. She is now concentrating on environmental activism in Latin America with an emphasis on the two countries she lived in between 1962 and 1972: Brazil and Panama. Most of her work draws from scholarship on social constructionism.
Among her publications are two books, Hidden Arguments: Political Ideology and Disease Prevention Policy (Rutgers University Press, 1988) and Uncertain Hazards: Environmental Activists and Scientific Proof (Cornell University Press, 2000).
