About me

I'm a postdoctoral fellow in the Psychology Department at Northeastern University. I do research on visual perception, working with Peter Bex, studying spatial vision, localization, and eye movements. I got my Ph.D. in 2015 from UC Berkeley working with David Whitney.

Visual localization

How does the brain register the locations of the objects that we see in the world? Object positions are primarily assigned based on where they fall on the retina, but perceived location can be influenced by a number of additional factors, such as surrounding motion, visual attention, and stimulus history. Recently, I have examined individual differences in the errors that people make when localizing visual targets, and how the visual system maintains perceived alignment between the two hemifields.

Eye movements

Eye movements are essential for interacting with our environment. The eyes can move from one location to the next using rapid movements called saccades, which can be made up to 2-4 times per second. Do these eye movements show similar errors to those made by the visual system? I have shown that eye movements can reflect individual differences in localization errors, and in some conditions, can be influenced by motion-induced position shifts.

Translational research

Can we use our understanding of eye movements and localization to benefit individuals with visual impairments? Localization deficits are implicated in a number of visual disorders, such as strabismus and amblyopia, and a complete understanding of this process can help guide diagnostic tools and treatments for these deficits. Recently, I have been investigating new measurement procedures for evaluating eye movements in individuals with strabismus.
