The current standard of care for treating amblyopia in kids is limited by poor compliance, recurrence, and a loss of efficacy once children enter adolescence. The overall goal of our work is to discover new treatments for amblyopia and other visual disabilities by leveraging reverse translation approaches and principles of homeostatic plasticity in the mature nervous system. Using these approaches we have found that (1) transient loss of vision via pharmacological inactivation of the retinas drives rapid homeostatic potentiation of thalamocortical synapses in mature mice, (2) temporary retinal inactivation can promote visual recovery beyond the canonical critical period in two preclinical models of amblyopia, and (3) selective inactivation of a subset of retinal cells can drive pathway-specific homeostatic plasticity that may address asymmetries in visual function observed in human amblyopia. Our work demonstrates the utility of using different forms of visual deprivation to drive plasticity in the brain to promote visual recovery and enhancement.

She completed her postdoctoral training in the Department of Brain and Cognitive Sciences at MIT and a visiting lectureship in the Neuroscience Department at Wellesley College. She launched her independent lab the Coulter Department of Biomedical Engineering at Georgia Tech and Emory as an Assistant Professor in Fall 2021. Her research focuses on discovery of new plasticity mechanisms in the mammalian brain as well as translational applications of plasticity for promoting vision restoration in preclinical models of blindness and visual impairment.
