Nange Jin, M.D., M.S., Ph.D., is a Research Assistant Professor at the University of Houston College of Optometry. His research focuses on retinal neurobiology, visual neuroscience, chronobiology, and the neuromodulatory regulation of electrical synapses in retinal circuits. He has extensive expertise in electrophysiology, single-cell and paired patch-clamp recordings, live imaging, two-photon microscopy, genetic mouse models, and computational approaches to visual circuit function. Dr. Jin’s work has helped define how connexin36-mediated rod–cone coupling, dopamine, melatonin, circadian clocks, and light adaptation regulate retinal signal processing, image- and non-image-forming vision, and visual performance. His publications include studies in Science Advances, PNAS, Cell Reports, The Journal of Physiology, and The Journal of Neuroscience. He has contributed to multiple NIH-funded projects investigating rod/cone pathway plasticity and retinal electrical synaptic connectivity.
