Lorenzo Vidino



Dr. Lorenzo Vidino is the Director of the Program on Extremism at The George Washington University. An expert on Islamism in Europe and North America, his research over the past 20 years has focused on the mobilization dynamics of jihadist networks in the West; governmental counter-radicalization policies; and the activities of Muslim Brotherhood-inspired organizations in the West.

A native of Italy who holds American citizenship, Dr. Vidino earned a law degree from the University of Milan Law School and a doctorate in international relations from Tufts University’s Fletcher School of Law and Diplomacy. He has held positions at Harvard University’s Belfer Center for Science and International Affairs at the Kennedy School of Government, the U.S. Institute of Peace, the RAND Corporation, and the Center for Security Studies (ETH Zurich).

The author of several books and numerous articles, Dr. Vidino’s most prominent works are on the Muslim Brotherhood in the West. His first is The New Muslim Brotherhood in the West (Columbia University Press, 2010). The book offers a comparative study of Islamist organizing in various Western countries as well as the wide-ranging public policy responses by Western leaders. His most recent book, The Closed Circle: Joining and Leaving the Muslim Brotherhood in the West, (Columbia University Press, 2020) is based on interviews with former members of the group, offering an unprecedented inside view into how one of the world's most influential Islamist groups operates, and how some individuals made the difficult decision to leave. The book has been translated into Arabic, Spanish, French and Italian.

Dr. Vidino has testified before the U.S. Congress and other parliaments; advised law enforcement officials around the world; and taught at universities in the U.S. and Europe. He regularly provides commentary to diverse media outlets (including The New York Times, The Washington Post, The Wall Street Journal, PBS, CNN, Fox News, MSNBC, BBC, Al Jazeera, Al Arabiya...) and is a columnist for the Italian newspapers La Repubblica and La Stampa. 

In 2016, he was appointed by Italian Prime Minister Matteo Renzi as Coordinator of the National Commission on Jihadist Radicalization.
