Research Interests

Dr. Nicholas Port completed his undergraduate training at NYU's Center for Neural Science (1990) and completed his  pre-graduate training at the Centre for Cognitive Neuroscience at Oxford University (1991). He received his Ph.D. in Neuroscience from the University of Minnesota in 1997. Dr. Port did his postdoctoral training at the Laboratory for Sensorimotor Research at the National Eye Institute. Dr. Port joined the faculty of the IU School of Optometry in August 2005. Dr. Port's research interests are centered on using the visual-saccadic system as a model for how the nervous system processes sensory information and produces action. His laboratory is currently following two lines of research. The first line studies the underlying neurophysiology of how we maintain a stable visual world while the nervous system scans the visual world with saccadic eye movements every third of a second. The second line of research tests whether mathematical models of information processing and decision-making accurately describe the underlying neurophysiological computations.
