Dr Matt J Dunn
Lecturer, Deputy Director of Postgraduate Research
My principal research interests are in disorders of visual perception, oculomotor neurophysiology, and experimental psychophysics. I have a particular focus on understanding the neuropsychology underpinning perceptual experience in infantile nystagmus. Much of my work involves eye and/or body tracking, combining new technologies with classical psychophysical methods to understand the complex relationship between perception and action. I am an optometrist, and typically recruit patients with orthoptic or perceptual disorders to better understand visual physiology. I am also the author of the popular ophthalmology e-textbook Dunn Vision Reference.
