I completed my Ph.D. in homotopy theory at the University of Toronto in 1989. My supervisor was Professor Paul Selick. My current research interests are related to the invariant theory of finite groups. My collaborators include Eddy Campbell, Peter Fleischmann, Ian Hughes, Müfit Sezer, Gregor Kemper and David Wehlau.

The IMSAS has regular mathematics seminars.
