I am an assistant professor with the Utrecht University department of Sociology. The focus of my research is understanding (online) extremism and threats of violence by using computational linguistics. I hold a PhD from the UCL Department of Security and Crime Science. I aim to develop solutions to better understand and counter radicalisation, extremism, terrorism, and other forms of grievance-fuelled targeted violence. I am also interested in improving research transparency within and beyond the field of crime science.
