My research focuses on sensory substitution, mechanisms of neural adaptation, and plasticity. Sensory substitution devices are capable of transmitting visual information for people who are blind. Brain plasticity is a phenomenon that typically occurs when people learn to use these devices. In the context of my research, I have tested several different sensory substitution devices in a variety of contexts and spatial tasks, such as obstacle detection and negotiation, object recognition and spatial localization, visual acuity, maze learning, and virtual navigation. Using fMRI, my research has highlighted the recruitment of a similar navigation network in people who are congenitally blind, as well as demonstrating volumetric differences between sighted and congenitally blind individuals in terms of this network. We are interested in the link between brain plasticity and different kinds of perceptual learning. We also work on the role of visual experience in shaping the neural networks involved in navigation.
