Thomas M. Langley

Professor of Mathematics

Dr. Tom Langley's areas of expertise include combinatorics and algebra. His research activities cover symmetric functions, algebraic combinatorics, and cwatsets, a subset of binary space first discovered at Rose-Hulman in the 1980s. Prior to his career in mathematics, Dr. Langley earned degrees in electrical engineering and was an electrical engineer for the Jet Propulsion Laboratory in Pasadena, Ca. He is the editor of the Rose-Hulman Undergraduate Mathematics Journal, the longest-running publication of original undergraduate-only math research in the U.S.
