Current Research Interests Functional localisation of the human visual cortex using magneto-encephalography. Retinal physiology and visual function. Computational models of human motion perception. Visual performance and driving. Projects within the above areas are currently funded by grants from Fight For Sight, Institute of Ophthalmology, London.
