I was born in the northern Norwegian town of Narvik in 1977. At age 16 I won a scholarship to attend high school in Poitiers, France. From there I went to Balliol College, Oxford, and did a BA in Egyptology and Classical Hebrew followed by an M.Phil. in Modern Middle East Studies (with Arabic). In the summer of 2001 I joined the Norwegian Defence Research Establishment (FFI) as a research fellow. From 2003 to 2007, while based at FFI, I was a PhD student at Sciences-Po in Paris, where I wrote a thesis on Jihadism in Saudi Arabia under the supervision of Professor Gilles Kepel. 

Although I have been affiliated with FFI since 2001, I have spent several years in the United States on various fellowships. I was a postdoctoral fellow at Princeton University (Transregional Institute) in 2007-8, a fellow at Harvard Kennedy School (Belfer Center) in 2008-09, a member of the Institute for Advanced Study in Princeton in 2009-10, and a Zuckerman fellow at Stanford University (CISAC) in 2012-13. Since September 2015 I have been an adjunct professor in the Department of Political Science at the University of Oslo.

I have published widely on various aspects of Islamist militancy. I wrote Jihad in Saudi Arabia (Cambridge  2010) and co-authored the Meccan Rebellion (Amal 2011) and Al-Qaida dans le texte (Presses Universitaires de France, 2005). My articles have appeared in journals such as the American Political Science Review, International Security, Journal of Peace ResearchInternational AffairsInternational Journal of Middle East Studies, British Journal of Middle Eastern Studies, The Middle East Journal, Middle East Policy, and Studies in Conflict and Terrorism. I have also written for the International Crisis Group and Oxford Analytica. I previously co-edited Jihadica, a blog that covers developments on jihadist websites.

I regularly advise governments on matters relating to Islamism and terrorism. I have testified in the British Parliament (2014), US Congress (2013), in the Canadian Senate (2005 and 2010) and in the Danish Parliament (2006). I testified before the Norwegian 22 July Commission and served on the Advisory Expert Group of Statoil's investigation into the In Amenas attack. I have also served as an expert witness in several terrorism trials in the United Kingdom.

Research interests

My work can be broadly described as actor-centered research on  Islamist militancy. I combine in-depth historical research, fieldwork and social science methods to analyze the origins, ideology and behaviour of violent Islamist groups, mainly of the transnational variety. Like most people I am interested in understanding why al-Qaida emerged when it did and why it continues to attract recruits. 

Much of my past work focused on the history of jihadism in Saudi Arabia. This was my PhD project, which in turn became a book.

I also have a long-standing interest in jihadi ideology, and I remain an avid collector and reader of jihadi propaganda past and present. See the publications page for my writings on the subject.

I have also done extensive research on Muslim foreign fighters, by which I mean people who travel abroad to fight in other Muslims' wars without necessarily engaging in international terrorism. At the moment I am completing a book about Abdallah Azzam and the history of the Arab fighters in 1980s Afghanistan. 

One of my main resarch interests at the moment is jihadi culture, by which I mean all the things militants do and consume in the underground when they are not fighting or justifying violence. This includes things like poetry, music, iconography, dream interpretation, dress, social practices, and rituals. I strongly suspect that these products and practices, many of which appeal to emotions more than the intellect, facilitate recruitment and group control. 

I am also working on a book about the history of militant Islamism from the 19th century to the present day. It is under contract with Penguin Press and Farrard, Straus and Giroux and will be completed in 2018.
