John S. Werner, Ph.D.

Clinical/Research Interests

Dr. Werner studies the neurophysiological computations and mechanisms that mediate human vision, particularly changes in color and spatial vision across the life span and in association with retinal and optic nerve disease. His work has demonstrated adaptive modifications of the visual system response to changes in signals due to aging of the eye's optics and retina. His laboratory has developed state-of-the-art methods for imaging the human retina of the living eye at a cellular scale. Dr. Werner clinical and research interests include visual psychophysics.
