Aline Gubrium is an Assistant Professor of Public Health and a medical anthropologist at the University of Massachusetts, Amherst, USA. Gubrium uses participatory, digital, visual, and ethnographic narrative methods to study the sexual and reproductive health knowledge and decision-making of marginalised women and youth. She has done research with African-American women living in a southern rural community, women using Depo-Provera contraception, and Latino/a youth addressing barriers to sexual communication and sexuality education. Her research is driven by the question of how research participants view, make sense of, and respond to their sexual and reproductive health experiences. Krista Harper is an Associate Professor in the Department of Anthropology and the Center for Public Policy and Administration (CPPA) at the University of Massachusetts, Amherst, USA. As an ethnographer, Harper explores issues related to the cultural politics of the environment, cities, and food systems. She is the author of Wild Capitalism: Environmental Activists and Post-socialist Political Ecology in Hungary (2006). Harper has led projects using participatory digital research methods such as Photovoice to study environmental issues in a Hungarian Roma neighbourhood, school food programs with youth in western Massachusetts, and civic organisations working on urban gardens and heritage preservation both nationally and globally.
