I study human vision using psychophysics (the measurement of the limits of performance), computational modelling and brain imaging. My basic research examines how we recognise objects (such as faces or words) in central and peripheral vision. My applied research is concerned with vision in neurodevelopmental disorders (such as autism) and psychiatric illness (such as schizophrenia). In Auckland my work has focused on measuring vision in children - using technologies like eyetracking, virtual reality and tablet computers - and developing treatments for disorders such as amblyopia ("lazy eye")
