Research Focus


My laboratory studies how the fibers connecting the eye to the brain are damaged in diseases such as trauma, stroke, multiple sclerosis, and the most common cause of irreversible blindness in the world, glaucoma. These fibers, the axons of the optic nerve, cannot regenerate in humans, and so understanding how they degenerate in disease is the first step to finding new therapies. Based on what we have discovered, we have been actively developing new drugs that are able to prevent visual loss from these blinding diseases. Given that many of these diseases have no proven therapies, we hope that the knowledge we gain will lead to effective treatments in the future.
