Research Interests
My research concerns:
spatiotemporal vision
motion perception
first and second-order vision
global perception
computational models of visual processing
efficiency of visual performance
ocular accommodation
visual development
eye movements
low vision
glaucoma diagnostics
Teaching
My teaching interests include visual psychophysics, visual optics, geometrical optics, environmental optics, clinical electrophysiology of vision.
Education & Work Experience
I graduated in physics from Sofia University, Bulgaria. I worked at the Institute of Physiology, Bulgarian Academy of Sciences, where I completed my PhD thesis on spatial and temporal characteristics of human vision. Since 1998, I have been working at the Department of Vision Sciences, Glasgow Caledonian University. In 2007 I was promoted to Professor of Visual Neuroscience.
