The primary goal of my research is to understand neuroplasticity, the fundamental dynamic processes that allow the brain to adapt to inputs from, and changes in, the environment. I investigate the neuroplasticity in the developing and mature visual system in normal and diseased states. I am particularly interested in understanding the brain mechanisms that cause abnormal eye movements, strabismus (eye misalignment), and amblyopia (lazy eye), as well as how to treat these diseases. My laboratories use a variety of techniques, including anatomic, behavioural, psychophysical, and neuroimaging methods, to investigate how the normal brain functions and how these brain functions change in the diseased state. More recently, my research has expanded to include using chromatic pupillometry as a novel tool to investigate different visual and neurological disorders, evaluating the utility and cost-effectiveness of universal vision screening in kindergarten children, as well as developing an innovative mindfulness training program to enhance physician well-being.
