My research uses results from Classical groups, K-theory, Number theory, Quadratic forms, Coxeter groups and representation theory. In particular, with respect to classical groups, my work has focused on the theory of the group SL_2 over number rings and the behavior of its subgroups related to ideals in the rings. I am still interested in some unresolved questions from K-theory, concerning SL_2 over rings. More recently I have done some work on convex geometries on root systems related to Coxeter groups. I have compared several natural convex closure operators on these root systems, and considered the question as to when they satisfy an anti-exchange condition, defined by Edelamn and Jamison.
I am currently working on the representation theory of an interesting algebra related to the n by n matrices over the ring R $\otimes$ R, where R is the ring of integers of a number field. The representation theory can be explored using the results of Dyer on Category C, and has interesting connections with the number theory of the rings.
