Kathryn Nyman

Associate Professor of Mathematics


PhD, Mathematics, Cornell University, 2001

MS, Mathematics, Cornell University, 1998

BA, Math, Carthage College, 1995


Professor Nyman’s research is in the areas of algebraic, geometric and topological combinatorics. She is especially interested in questions involving people’s preferences, from which piece of cake one prefers, to their preference of election candidates.
