Age-related macular degeneration (AMD) is the most common cause of vision loss in the developed world. Central visual field loss due to diseases such as AMD is a large and growing problem. It is also associated with higher risk of

Challenges in Head-Free Eye Tracking in Health & Disease
This project is focused on investigating sources of error and potential improvement methodologies for head-free eye tracking, particularly in individuals with known oculomotor deficits
Vestibular Function in AMD: Verticality Perception
To accurately perceive one’s own state and that of the surrounding environment, visual, vestibular and somatosensory inputs must be appropriately weighted and dynamically reweighted depending on the environment and task difficulty, as well as signal reliability (and availability). Aging is
Effects of Noise Exposure Across the Lifespan on Balance and Stability in Older Adults
Falls in older adults are common, have high societal and monetary costs, often lead to injury and can even be fatal. It is known that noise can damage the vestibular periphery resulting in postural instability and compromised balance. This project
Robotic Oculomotor Simulator
Current eye tracking and calibration algorithms do not accommodate eccentric viewing and the capacity for accurate eye tracking is difficult to assess in individuals with central visual field loss, and few studies of naturalistic oculomotor behavior exist. To address this
Coordination of Eye and Head Movements in Central Field Loss
This project investigates the interaction between central field loss (CFL) and vestibular function.
Characteristics of Smooth Pursuit in Individuals with Central Field Loss
This project investigates the properties of smooth pursuit eye movements in individuals with macular degeneration. Commonly believed to be a fovea-linked eye movement, smooth pursuit has not been previously investigated in individuals with central field loss, despite its importance for
Labs
Eye-Head Movement Laboratory
Our laboratory is interested in how changes in visual and/or vestibular function affect eye/head coordination, balance, and mobility, particularly in aging. We are currently pursuing two main lines of research: 1. The effects of central visual field loss on eye
Centers
Rehabilitation Engineering Research Center
The Center’s research goal is to develop and apply new scientific knowledge and practical, cost-effective devices to better understand and address the real-world problems of blind, visually impaired, and deaf-blind consumers. The RERC has many ongoing R&D projects and collaborative
