My research interests are placed at a number of intersections, such as senses, modalities and effectors. Currently in my lab, we are investigating the effects of central vision loss on visual/vestibular interactions. Specifically, we are interested in how changes in the visual and vestibular senses are reflected in eye-head coordination and how these changes, in turn, affect tasks of daily living. To study these questions, my lab uses a mixture of vestibular and visual stimulation, eye and head movements, psychophysics and other behavioral measures.
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 problem, we are developing a binocular robotic model of the human eyes that can simulate fixation and eye movements with an eccentric preferred retinal locus in one or both eyes and allow for precise assessment of eye tracking performance of head mounted computer vision-based eye tracking systems.
There is continuing debate as to whether smooth pursuit relies on the foveation of a moving target, especially when the target is compact. Previous studies have shown that gaze is placed on the center-of-mass of a target during saccadic eye movements. This research aims to understand whether eye...
This project investigates the interaction between central field loss (CFL) and vestibular function.
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 tracking moving objects, such as vehicles or pedestrians on a busy street.
The project investigates motion perception in individuals with vision loss due to central retinal lesion, but who retain healthy peripheral retina. Healthy peripheral retina is exquisitely sensitive to fast speeds, however, there is limited and conflicting information about motion processing in...
In this project we try to gain a better understanding of what visual strategies people use to gather information in the world.
