Dr Matt J Dunn
My principal research interests are in 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. As an optometrist, I 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.

I am registered as a STEMnet ambassador, and provide public talks on vision science and perception.
I teach clinical optometry and orthoptics, and have previously delivered the Visual Perception lecture series at Cardiff University. I am recognised as a fellow of the Higher Education Academy (FHEA).
