Research Interests

My main research interests are in noncommutative algebra, more specifically the structure of noncommutative rings and algebras and of their representations. At present my focus is primarily on Hopf algebras, on quantum groups and on homological questions, but in the past I have worked on symplectic reflection algebras, on enveloping algebras, on rings of differential operators, on group rings, and on invariant rings, as well as on "abstract" noetherian ring theory, and I maintain an active interest in all these topics.
