Career
He was previously a research director at the French National Center for Scientific Research and a lecturer for both the School for Advanced Studies in the Social Sciences and the Institut d'Études Politiques de Paris . From 1984 to 2008, he was a consultant for the French Foreign Ministry. In 1988, Roy served as a United Nations Office for Coordinating Relief in Afghanistan consultant. Beginning in August 1993, Roy served as special Organization for Security and Co-operation in Europe representative to Tajikistan until February 1994, at which time he was selected as head of the OSCE mission to Tajikistan, a position he held until October 1994. Roy is the author of books on Iran, Islam and Asian politics. These works include Globalized Islam: The search for a new ummah, Today's Turkey: A European State? and The Illusions of September 11. He also serves on the editorial board of the academic journalCentral Asian Survey. His best-known book, L'Echec de l'Islam politique , is a standard text for students of political Islam. Roy wrote widely on the 2005 civil unrest in France, rebutting the suggestion that the violence was religiously inspired. He argues that Islamism is merely the rubric under which troubled youth enact their violent inclinations. A view adamantly opposed by Roy's intellectual rival, Gilles Kepel. According to Judith Miller, in the wake of the September 11 attacks Olivier argued that militant Islamism of the type represented by Al Qaeda had peaked and was fading into insignificance. His book Secularism Confronts Islam offers a perspective on the place of Islam in secular society and looks at the diverse experiences of Muslim immigrants in the West. Roy examines how Muslim intellectuals have made it possible for Muslims to live in a secularized world while maintaining the identity of a "true believer." In 2010 he published , an analysis of religion, ethnicity and culture and the results when these part ways. After the Charlie Hebdo shooting he argued that most French Muslims were committed to prevent violence, and after the November 2015 Paris attacks, he wrote a strategic analysis of ISIS and the fight against it, published in The New York Times. In 2017, Roy's assertion that jihadi terrorism is only loosely connected to Islamic fundamentalism was criticised by French scholar Gilles Kepel, who said that Roy neither speaks Arabic nor looks into the Salafi doctrine behind the jihadism. Roy has said "I have been accused of disregarding the link between terrorist violence and the religious radicalisation of Islam through Salafism, the ultra-conservative interpretation of the faith. I am fully aware of all of these dimensions; I am simply saying that they are inadequate to account for the phenomena we study, because no causal link can be found on the basis of the empirical data we have available."
