Her current research traces the emergence of violence as an object of public health science, practice, and policy at the Centers for Disease Control and Prevention and other federal agencies. She examines the evolving political, scientific, and structural factors that shaped the production of both knowledge and ignorance about American violence in the late twentieth and early twenty-first centuries. Joanna holds a bachelor’s degree in literature and film from the University of Notre Dame and a master’s in history from the University of Louisville. She has previously studied popular and policy responses to mass gun violence and the role of collective memory in peer-to-peer breastfeeding support.
