Professor of Vision Science, Newcastle University

My central research interest is binocular vision and the perception of 3D stereo depth. I'm interested in what happens in our brain when images from the two eyes are combined and compared so as to give this depth percept. I construct mathematical models of the neuronal computations which support this process, and carry out detailed measurements of human perceptions in order to test these models and relate them more closely to what is known about brain physiology. I'm increasingly using this expertise to look at how today's new 3D displays can be used so as to improve viewer experience. I'm also interested in how visual perception can be altered in various clinical conditions, for example strabismus (often known as squint in the UK) and epilepsy. Finally, in 2013 I started a new research programme examining 3D vision in an insect, the praying mantis. Learning more about vision in this simple organism may help us design better 3D vision for robots, and may also help us understand our own more complex abilities.
