Background

Ian’s research interests include using computer modelling and experimental psychology to study the human visual system. In particular, he is interested in gaze control, visual short-term memory, face perception, visual task planning, image quality assessment, multimodal binding, the impact of ageing on visual performance, and the computations performed in the early visual system.
