I have been working in NLP and AI for over 30 years. Before joining the University of Cambridge on an EPSRC Experienced Researcher Fellowship (2015-2020) I spent the early part of my career in Japan (1996-2012). I was a Toshiba Fellow, a postdoc at Tokyo University with Junichi Tsujii and Associate Professor at the (then) newly formed National Institute of Informatics where I led the NLP lab for 12 years before returning to the UK on a Marie Curie Research Fellowship. As an undergraduate I studied for a BSc. in Computer Science at the University of Leeds (1992). I received an MSc in Machine Translation (1994) and a PhD in Computational Linguistics (1996) from the University of Manchester (UMIST) for my research on English-Japanese Lexical Transfer using a Hopfield Neural Network. My current roles are Professor of NLP, co-leading the Language Technology Lab at Cambridge, Professorial Fellow at Murray Edwards College, and also Chief Scientist at Trismik, a spinout I co-founded and which launched in May 2025.
My work focuses on natural language processing and machine learning. My research interests are broadly in creating better models for natural language understanding (see recent publications on Google Scholar). Recent areas of focus include LLM evaluations - including adversarial attacks and policy violations, understanding uncertainty, reasoning and issues around synthetic personalities. I also have a long running interest in NLP applications particularly in biomedicine and epidemiology that involve state of the art models and illustrate interesting challenges.
Prospective PhD students: I am always interested to supervise new NLP projects on the PhD in Computation, Cognition and Language. Before contacting me please make sure that you meet the minimum requirements and take time to check out my publications. The work we do in my team is technical and experiment-based so please apply only if you have strong programming skills. In your email please send a CV with a brief statement of research interests. Please note the application deadline and documents you need to submit with your application. Note for 2026 applicants: I will accept 2 or 3 PhDs in 2026, and also the MPhil by Research in language sciences offers places to applicants with an NLP background. This can be a great springboard to PhD research.
Enquiries for postdoctoral opportunities are welcome. When needed I can help explore funding sources for fellowships from UK, EU and other agencies.
Over the years many people have contributed to the research and publications in my lab. Here's a list of current students, postdocs and alumni.
