Research Associate, Minderoo Centre for Technology and Democracy

Dr Stefanie Ullmann is a Research Associate on the Horizon Europe project AI4Trust at the Minderoo Centre for Technology and Democracy, University of Cambridge. Her research is centred on the interplay of language, technology and society. More precisely, she is interested in how language is used in political/conflict contexts; how digital media and AI systems mediate language and discourse (including harmful content); what strategies (technical, ethical, regulatory) can help mitigate harms (hate speech, bias) in online/AI-mediated communication. Dr Ullmann has co-developed several mitigation tools and strategies to combat harmful content such as a quarantining tool for online hate speech, bias mitigation strategies for neural machine translation and a counterspeech generator. Her work has appeared in multiple collected volumes and journals including The Language of Crisis, Artificial Intelligence and its Discontents, Discourse & Communication, Language & Politics and Ethics & Information Technology. She is the author of a monograph called Discourses of the Arab Revolutions in Media and Politics and editor of Counterspeech: Multidisciplinary Perspectives on Countering Dangerous Speech.
