Research Area



Research Interests

M. Dyer works in the general area of group theory and representation theory. Research is focused on Coxeter groups, Iwahori-Hecke algebras and their relationships with representation theories from algebraic groups, semisimple and Kac-Moody Lie algebras and groups, and quantum groups.
