Christopher Sadowski
Associate Professor
Christopher Sadowski earned a BS and PhD in Mathematics at Rutgers University - New Brunswick, where he also worked as a teaching assistant and lecturer. He joined the faculty of Ursinus College in 2014 as a visiting assistant professor.
Christopher’s research interests are primarily in vertex operator algebra theory and its applications in the study of affine Lie algebras. He is also interested in the theory of partitions, and how partition identities can be interpreted in the study of vertex-algebraic structures.
