Eye movements and Accommodation Patterns in Strabismus
Strabismus misaligned eyes is a common developmental condition in young children that can lead to amblyopia or poor vision and other forms of low vision. This project looks at the eye movements in relation to accommodation or focusing power in these patients to determine predictors of strabismus and outcome of treatment, with the goal of improving early detection, intervention and treatment.

Fixational and Functional PRL in Central Vision Loss
Individuals with central vision loss (commonly due to age-related macular degeneration), must use viewing strategies using peripheral vision. Patients often adopt a preferred retinal locus (PRL) for visually guided behavior. While the are clinical measures for estimating the PRL, little is known about use in the real world. Our research seeks to characterize this natural behavior and inform visual rehabilation techniques.
Parafoveal Crowding
Crowding increases with eccentricity, and is most readily observed in the periphery. During natural, active vision however, central vision plays an important role. Measures of critical distance to estimate crowding are difficult in central vision, as these distances are small. Any overlap of...
SKERI-VF
Walker et al (Renninger, Psomadakis, Dang & Fletcher, 2008) suggested a novel method to estimate the monocular scotoma area from perimetry data in macular degeneration based on (i) an optic-disc based estimation of the location of the fovea and (ii) the increase...
Mentors
I completed my BS in Chemical Engineering at MIT and PhD in Vision Science at UC Berkeley. At Berkeley, I studied with Dr. Jitendra Malik using psychophysics to validate computer vision algorithms. During my postdoctoral training with Drs. Preeti Verghese and James Coughlan at Smith-Kettlewell, I developed a computational model of eye movements and continue to apply and develop these models to predict how changing eye movements can improve vision for people different retinal diseases. My most recent project examines the impact of central vision loss on eye-hand coordination. The ultimate goal is to take what is learned in the laboratory and translate it into low vision rehabilitation therapies.
