I am a lecturer (assistant professor) in Computing at the Centre for Argument Technology of the University of Dundee. My general areas of interest are argumentation and reasoning (both human and artificial), with a particular focus on digital tools for critical literacy. My research draws on a variety of methods from artificial intelligence, linguistics, logic, and philosophy, such as machine learning and corpus annotation. I am the author of over 40 publications and taught at the Universities of Amsterdam and Dundee on a range of different subjects. As Principal Investigator and Co-Investigator, I have won over £4m in grant funding, from sources such as Dstl in the UK and IARPA in the US. Since 2023, I am a Fellow of the Higher Education Academy in the UK.
