His current research focuses on comparative reciprocal polarisation, extremism, and radicalisation. He is the Scientific Coordinator of the European Commission (EC)-funded Drive project, which explores Muslim minority and ethnic majority issues related to polarisation and extremism, and the Principal Investigator of the EC-funded Protone project, which explores protecting Abrahamic religious places of worship in Europe. His most recent book, Islamophobia and Securitisation: The Dutch Case, was published in August 2022 by Palgrave-Pivot-Springer (with L. Welten). His previous books include Countering Violent Extremism: The International Deradicalization Agenda, which was published by Bloomsbury in 2021, and Islamophobia and Radicalisation: A Vicious Cycle, which was published in late 2019 by Hurst and co-published by Oxford University Press in New York. Other recent publications include examining the waves of ‘Islamist extremism’ in the UK in Journal of Contemporary European Studies (2023), the impact of the Prevent Duty on Muslim university students in the UK (with I. Awan and J. Marsden) in Race Ethnicity and Education (2023), the theorisation of ‘structural radicalisation’ in relation to violent extremism in southeast Turkey (with K. Ovet and J. Hewitt) in Studies in Conflict and Terrorism (2022), and how the Brexit vote in the UK and Refugee Crisis events in Germany shaped tolerance towards immigrants and minorities in Ethnic and Racial Studies (2021).
