I am a PhD student at the UCL Department of Security and Crime Science. I also work as a research assistant on the ERC-funded GRIEVANCE project. The focus of my research is understanding threats of violence by using computational linguistics. 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: check out the open science seminar series I co-organise.
