About me

I'm an assistant professor in the Department of Psychology at the University of Toronto Mississauga. I do research on visual perception, with a focus on individual differences, spatial vision, eye movements, and applied perception.

Individual differences

Why do people sometimes disagree about what they see? My research examines individual differences in fundamental visual processes and the implications they have for perception in the real-world. Many real-world settings can benefit from an individual differences approach,including digital readability, collaborative tasks, and visual impairment. Specific research areas include:

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.
