Profile
Biography
My research investigates how we encode and process visual information to create our experience of living in a three-dimensional world. This research is used in the development of virtual and augmented reality, and particular in the creation of assistive technology for people with visual impairments. It is also applied in the development of neural network models of visual processing, and in the understanding of the sensory basis of migraine.
