Bio

Dr. Jordan Pola earned his B.S. in Philosophy and his M.A. and Ph.D. in Experimental Psychology at Columbia University. After completing his doctoral research on visual perception and saccadic eye movements, he did postdoctoral work at Johns Hopkins School of Medicine on oculomotor brainstem neurophysiology. Dr. Pola came to SUNY College of Optometry in 1974 and is currently Distinguished Teaching Professor in the Department of Biological and Vision Sciences. He is Instructor of Record in the Visual Function: Sensorimotor I course for second year OD students and teaches a variety of courses in the M.S. and Ph.D. vision science program and in the C-step program. Along with teaching, Dr. Pola has mentored many Research, M.S. and Ph.D. students. He has also served as a member of numerous College committees; as Chairperson of the Policy, Animal Care, Qualifications and Students Committees; and as Presiding Officer of the College Graduate Faculty. The recipient of Federal and SUNY research grants, Dr. Pola has published in the areas of oculomotor behavior (saccades, smooth pursuit, OKN and fixation), oculomotor neurophysiology, models of the oculomotor system, perceptual processes associated with eye movements, and stimulus control and dynamics of accommodation. He has been a reviewer and referee for Federal granting agencies and scientific journals concerned with vision, visuomotor behavior and neurophysiology, and has served as a member of the ARVO Scientific Advisory Committee and as a chairman of the ARVO Eye Movement Program Committee. He is currently a member of the Society for Neuroscience, the Vision Sciences Society and the Association for Psychological Science.
