Current Research

Professor Lewis's book, "How Insurgency Begins: Rebel Group Formation in Uganda and Beyond," was published in 2020 (Cambridge University Press, Studies in Comparative Politics Series). It 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. It was recommended as a best book of 2020 at the online magazine Political Violence @ A Glance.

In addition to continuing research on the start of armed conflict, her other projects seek to understand how information and beliefs travel through word-of-mouth networks in rural communities, and how states administer and monitor their peripheral regions. Her research articles have won several major awards.
