Jytte Klausen

Jytte Klausen is the Lawrence A. Wien Professor of International Cooperation at Brandeis University and an Affiliate at the Center for European Studies at Harvard University. Her most recent books are "The Cartoons That Shook the World" (Yale University Press 2009) about the Danish cartoons of the Prophet Muhammad and the worldwide protests that followed their publication, and "The Islamic Challenge: Politics and Religion in Western Europe" (Oxford University Press 2005, pb. 2007), which was translated into German and Turkish.

Klausen is the founder of the Western Jihadism Project, a data collection and archive focused on Islamist Islamist extremist groups in the West. She leads a team at Brandeis University who are studying Islamist terrorist networks, funded initially by the UK Home Office, and now by an award from the National Institute of Justice at the U.S. Department of Justice.

Klausen was a British Academy Fellow at Nuffield College, Oxford University (2003), and a Bosch Public Policy Fellow at The American Academy in Berlin (2004). She has a PhD from the New School for Social Research (1992) and a BA and MA from the University of Aarhus, Denmark. In 2007, Klausen received the Carnegie Scholars’ Award for research on the integration of Muslim faith communities in Europe.

Klausen has written for Foreign Affairs, the Wall Street Journal, the Boston Globe, and other national and international outlets, and she is a regular commentator on the BBC, Voice of America, and other U.S. and international media. She has also frequently been consulted by government agencies in the U.S. and Western Europe.
