Biography

Mathieu Chollet is a Lecturer in Healthcare Technologies in the School of Computing Science of the University of Glasgow. His research is focused on social virtual agents – virtual characters capable of interacting with users through dialogue and non-verbal behaviour – and social signal processing – the application of signal processing and artificial intelligence techniques to understanding facial, bodily, and vocal behaviour. In particular, his work deals with the generation of virtual humans’ socio-emotional behaviour and the assessment of their impact on users’ cognitive and emotional states, and the automatic assessment of users’ performances during human-agent interaction through multimodal machine learning. His research has a strong experimental focus, with application domains in social skills training, remote collaboration, and healthcare.

His background is in Computer Science and particularly Human-Computer Interaction, with a PhD at Telecom Paris (France) on socio-emotional behaviour planning models for embodied conversational agents funded as part of the EU FP7 TARDIS project. Before joining the University of Glasgow, he was an assistant professor in Computer Science at IMT Atlantique in the LS2N laboratory (Nantes, France), after post-doctoral appointments at the University of Glasgow’s Institute of Neuroscience and Psychology, the USC Institute for Creative Technologies, and a fellowship at the Tokyo National Institute of Informatics. His current research themes include the understanding of psychosocial stress during virtual social interactions, and the design and evaluation of pedagogical approaches for public speaking training based on virtual reality and artificial intelligence.
