Areas of Expertise

Political violence; ethnic conflict; state formation; Africa

Current Research

Professor Lewis's research examines why and how rebel groups form, with a focus on why many groups fail in the early stages, and what ethnicity has to do with it. Her book on these issues, "How Insurgency Begins: Rebel Group Formation in Uganda and Beyond," will be published with Cambridge University Press in 2020. Her other projects seek to understand how news and beliefs travel through word-of-mouth networks in rural communities, and how states administer and monitor their peripheral regions.
