About Dr. Williford

Jason Williford joined the University of Wyoming faculty in 2009. He came to the University of Wyoming from the University of Colorado at Denver.

His mathematical interests center around the interplay between algebra, finite geometry, and combinatorics. Association schemes and coherent configurations are generalizations of permutation groups that provide a framework in which this interplay is quite rich. Recently, he has focused on generalizing the necessary conditions for existence and subset bounds of association schemes to coherent configurations. He also studies extremal problems in graph theory that can be approached using constructions from finite fields and geometries.
