His work has been published by The New York Times, The Wall Street Journal, Politico, and The Dispatch, among others. The Daily Beast has described him as one of “the most trusted authorities on the al-Qaeda network because of his encyclopedic knowledge of terrorist biographies.” He previously served as a trainer for the FBI’s Counterterrorism Division.
