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, Müfit Sezer, Gregor Kemper and David Wehlau.


The SMSAS has regular mathematics seminars.
