Expertise & Public Engagement

Neumann has led research projects and authored or co-authored influential policy reports about the crime-terror nexus, online radicalization, foreign fighter networks, countering terrorist finance, terrorist defectors, and terrorist recruitment in Europe. The most recent example is “Prisons and Terrorism: Extremist Offender Management in 10 European Countries” (ICSR, 2020) (with Rajan Basra).

ICSR’s ground breaking research on foreign fighters – for which he served as principal investigator – has informed policy-makers across the world. In this respect, he has served as a senior consultant for the U.S. Mission to the United Nations during the process of crafting UN Security Council Resolution 2178 on “Foreign Terrorist Fighters”, and testified before a full ministerial session of the UN Security Council as well as several committees of the U.S. House of Representatives, the UK House of Commons, the German Bundestag, the Canadian House of Commons, and the European Parliament.

Neumann has served as an expert witness for the UK’s Crown Prosecution Service, Northern Ireland’s Public Prosecution Service, and Scotland’s Crown Office. He also holds fellowships and advisory positions with the Hedayah Centre in Abu Dhabi, the Global Center on Cooperative Security in Washington, and the Club de Madrid, the association of former Presidents and Prime Ministers.
