Overview
Research in my lab is focused on exposing the mechanisms underlying disorders of visual perception – including blindsight, Charles Bonnet Syndrome (hallucinations), visual dyslexia and infantile nystagmus. In particular, I am interested in the role of involuntary eye movements in perceptual (in)stability. My interest in eyetracking extends to the clinical application of eyetrackers in routine eyecare and neurology practice. I am the author of the popular ophthalmology e-textbook Dunn Vision Reference and am the founder and general coordinator of the International Society for Clinical Eye Tracking (ISCET).
We typically recruit patients with orthoptic or perceptual disorders in order to better understand visual physiology. If you have a neurological visual disorder and are interested in taking part in research, please click here for more information.
