Jack Cowan is Professor of Mathematics and Neurology at The University of Chicago. His research is concerned with understanding how circuits in the visual cortex process information, which he uses mathematics to investigate. Cowan developed a neural field theory with H.R. Wilson and then showed how to use nonlinear stability theory to analyze how patterns of stable activity could arise in neural networks.
