My dissertation research is a study of development researchers conducting human subjects experiments in Kenya. These experiments, typically randomized controlled trials (RCTs), are used by development economists, global health scholars, and other scientists to test the efficacy of various development interventions throughout the Global South. Over the course of nine months of ethnographic fieldwork in the United States and 12 months in Kenya, I used participant observation, interviews, focus groups, investigative methods, and archival research to study development RCTs as they are practiced and understood by academic researchers, field staff, and research subjects. A large amount of my time in Kenya was spent traipsing up and down hills with study enumerators in the beautiful Kenyan countryside.
