Terrorism-Joint Analysis Group (T-JAG)

About T-JAG



While global military campaigns are fighting terrorism on the ground, violent extremist networks are also active in the digital sphere. In this new era of information warfare and fake news, it has become increasingly important to focus on delivering information that is both factual and timely.

It is precisely for this reason that the Terrorism Joint Analysis Group (T-JAG) was formed at the GCSP in 2017.

The purpose of the T-JAG is to provide a more global approach to fighting terrorism. The group delivers timely analysis to both the public and private sectors on the global manifestations of terror. In doing so, it aims to bridge the gap between diplomats, military officers, policy makers, academics, and journalists who are active in the field of preventing violent extremism (PVE).





Our work involves:



T-Jag Methodology


  • Monitoring and analysing the activities of extremist networks, both online and offline;
  • Providing workshops and training on intelligence gathering, analysis, and open source investigations;
  • Publishing reports on our findings about past, current, and future challenges;
  • Organising dialogues and round table discussions about violent extremism in Europe and beyond;
  • Engaging with partners in external conferences, workshops and other events; and
  • Sharing information and cooperating with our audiences to reach a comprehensive understanding on specific topics;

Analysing and understanding terrorism is an art as much as a science; a knowledge as much as an expertise. The T-JAG beliefs in taking an interdisciplinary and practical approach, incorporating the wide variety of experts, knowledge and expertise that the GCSP has to offer.

Project team

The core team of the T-JAG consistently works together with the Fellows who joined the GCSP through the Global Fellowship Initiative. The team currently consists of manager Jean-Paul Rouiller, deputy and senior analyst Jean-Pierre Keller, as well as GCSP Fellows Hafez AbuAdwan and Andreea Stoian Karadeli who work with the T-JAG at a large capacity to enhance the reach, expertise and capabilities of the group.

His research focuses on understanding the complete structures, ideologies, modus-operandi and connections of local terrorist networks, Radical Islamic organizations, the ‘ethno-nationalists’ groups (eg. IRA, PKK, LTTE or ETA) and the remnants of the far-left (eg. 17N phantom group in Greece). As manager of T-JAG, Mr Rouiller has embarked on some of the most sophisticated research projects regarding Swiss and European Foreign Terrorist Fighters, the growing alt-right extremism, and the security and intelligence apparatus of the Islamic State.
