His research interests span the fields of computational vision, machine learning, epistemology of the artificial. More specifically, he has been involved in defining stochastic models of visual attention, gaze shifts and visuomotor behaviour in different realms such as video coding, expertise characterisation, and robotics. Recently, he has been investigating how value, intrinsic rewards and emotions can interact with visual attention behaviour. On these topics he has authored more than 100 papers in international refereed journals and conferences.
