Research Interests

My research is focused on the study of human visual system. In particular, I am interested in the role that neuronal inhibitory mechanisms have on our visual perception. These mechanisms can enhance the detection of the borders of an image, can reverse the perceived direction of motion, or can also suppress the image from one eye, avoiding double vision in people with strabismus. I use a combination of human psychophysics and computational modelling techniques to uncover the functional characteristics of these neuronal mechanisms in different visual functions such as motion perception, spatial vision, and stereo vision.

Other Expertise

I also have interest in other areas related to the visual system. These include the following areas in which I have made contributions: eye movements, face perception, and visual illusions. Most of my research to date has been basic science, but I am increasingly working in collaboration with clinicians to examine how variations in performance on simple perceptual tasks can give useful information about various clinical populations and to develop new clinical tests to detect alterations in the inhibitory mechanisms of the brain.
