Over the last couple of years I (and many fellow terrorism researchers with me) have been spending more and more time on studying right-wing extremism. But that does not mean that jihadist terrorism is no longer a problem. In a recent installment in the GTACC Speakers Series I gave an overview of the current state […]
Updates on the site
Recently I updated the site with some of the things I did in 2020. There was some publicity around my second book (notably an interview in the Dutch daily NRC), and I began to engage in the research and analysis of conspiracy theories and right-wing extremism. In the summer I joined the Verwey-Jonker Institute as […]
New book chapter out, another one on the way
Leuven University Press recently published the edited volume Militant jihadism: today and tomorrow. I added a chapter in which I’m making a projection about the modus operandi of jihadist terrorists in Europe in the coming years. Be sure to check it out, as well as the other contributions. It’s a really interesting collection and it’s […]
Issue Brief on the shooting at the Strasbourg Christmas market
On 11 December 2018, 29-year old French national Chérif Chekatt committed a terrorist attack with a firearm on a Christmas market in Strasbourg. Drawing on my database about jihadist terrorist attacks in the West, I wrote an Issue Brief to show that this attack was in most respects a typical jihadist shooting, even though it […]
Issue Brief on the knife attack at Amsterdam Central Station
Over the last months I have been compiling a database about jihadist terrorist attacks in Europe, Canada and the US from 2004 to the present. This database can contribute to terrorist threat assessments by identifying trends and patterns in the way jihadist terrorists commit attacks. More specifically, it can provide fact-based analyses that can help […]
Research report on jihadist modus operandi
In cooperation with the International Centre for Counter-Terrorism in The Hague I published a new research report on jihadist modus operandi. We often associate jihadist terrorism with suicide attacks, but in this report I try to demonstrate that most jihadist attacks in recent years in the West were not suicide attacks. Over the period 2004-2017 […]
The terrorist attacks in Catalonia
On 17 August Spain was struck by the most deadly terrorist attacks since the 2004 Madrid Bombings. I updated this site with some newspaper and radio interviews (in Dutch) and an article (in English) about these terrible atacks. You can find the interviews in the ‘media appearances’ section, and the article in the ‘commentary and […]
Gunstige recensies over ‘Radicalisering ontrafeld’
‘Radicalisering ontrafeld’ heeft gunstige kritieken gekregen in Trouw en in de Vlaamse krant Het Belang van Limburg. Trouw heeft het over een “inzichtelijk” en “helder en leerzaam boek” en wijst op de “kennis van zaken” en “soepele pen” van de auteur. Marcel Grauls heeft namens Het Belang van Limburg mijn boek besproken in een wekelijkse rubriek […]
