Dr. Wei Li received his medical degree in 1997 from Zhejiang University in China and his Ph.D. in Visual Neuroscience in 2003 from the University of Texas at Houston. He completed a postdoctoral fellowship at Northwestern University. Dr. Li is currently a Senior Investigator and Chief of the Retinal Neurophysiology Section at the National Eye Institute (NEI), National Institutes of Health (NIH). The long-term goal of his research is to study the mammalian retina as a model for the central nervous system (CNS) -- to understand how it functions in physiological conditions, how it is formed, how it breaks down in pathological conditions, and how it can be repaired. Dr. Li has focused on two research themes: 1) Photoreceptor structure, synapse, circuits, and development, 2) Hibernation and metabolic adaptations in the retina and beyond.
