Charles Lister was a visiting fellow at the Brookings Doha Center. His research focused on terrorism, insurgency and sub-state security threats across the Middle East, especially in the Levant. Recently, his work has been nearly exclusively focused on assessing the status of the conflict in Syria, especially the makeup of the anti-government insurgency and its various jihadi components.
