Currently he is working in the fields of computer vision and pattern recognition, where his main interest is in automatic recognition of human behaviour, specialising in the analysis of facial expressions. Recently he has applied this to the field of behaviomedics: diagnosing, monitoring, and treating medical conditions that alter human behaviour, or that can be treated more efficiently with technology that senses or synthesises human behaviour. In 2011 he was the leading organiser of the first facial expression recognition challenge, FERA 2011
and the first and second Audio-Visual Emotion recognition Challenges, AVEC 2011
, AVEC 2012
