Vision Impairment Research Laboratory


Our work includes all aspects of low vision research, creating an interdisciplinary environment in which we can answer complex and multi-layered questions that are relevant to the rehabilitation of individuals with visual impairment. Specifically, there is a focus on co-morbidities, such as hearing impairment or cognitive impairment. The goal of including multiple impairments in our research is to be able to make our results as generalizable as possible to the life and daily challenges of persons with sensory loss, their care providers, and the service providers that work with them.
