Dube’s research focuses on the political economy of development. She studies topics like the link between poverty and conflict and the role of trust and institutions in the spread of epidemics. In recent work, she has examined how community involvement affected responses to the Ebola epidemic in Sierra Leone. In other current projects, Dube uses big data to understand radicalization in the Middle East, and she experimentally examines strategies for improving community-police relations in the United States.
