The Roy Laboratory is focused on understanding how different retinal cell types work in concert to generate vision and how vision is impaired in diseases such as glaucoma and diabetic retinopathy. The lab uses a multidisciplinary and comparative approach to study the organization and function of neural circuits in the retina, retinal projections to the brain, and structural and functional anomalies within the retina in blinding diseases. The knowledge gained from these studies is used to identify molecular and neural targets for vision restorative therapies.
The lab is also developing novel imaging, computational, and virus-based gene delivery techniques for retinal research.
Before joining the John A. Moran Eye Center at the University of Utah, Dr. Roy completed a postdoctoral fellowship at the Duke University School of Medicine and worked as a senior research associate at Duke and as an assistant project scientist at the Stein Eye Institute at the University of California at Los Angeles.
