Susan Marie Hermiller is an American mathematician specializing in the computational, combinatorial, and geometric theory of groups.
Hermiller earned a bachelor's degree in mathematics and physics from Ohio State University in 1984.
She went to Cornell University for graduate study in mathematics, earning a master's degree in 1987 and completing her Ph.D. in 1992.
[1] Her doctoral advisor was Kenneth Brown, and her dissertation was Rewriting Systems for Coxeter Groups.
[1] In 2021, her joint research with Mark Brittenham disproved the longstanding Bernhard-Jablan conjecture in knot theory, demonstrating that a proposed algorithm for determining the unknotting number of a knot was not viable.
