Mr. Joscelyn has constructed dossiers for hundreds of terrorists during the course of his work. 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.” In 2007, he published a monograph titled, Iran’s Proxy War Against America, which details Iran’s decades-long sponsorship of America’s terrorist enemies. In 2008, he completed an exhaustive review of the Guantanamo Bay detainee population, cataloging and analyzing thousands of pages of declassified documents.
