I am currently an Associate Professor, with tenure, in the Department of Applied Mathematics at the University of Western Ontario. In addition, I am an Honorary Professor in the Department of Computer Science and an Associate Researcher with the Boundary Layer Wind Tunnel Laboratory. I received tenure on July 1, 1993. My initial appointment was on July 1, 1987, when I was hired directly out of graduate school, and my contract was renewed July 1, 1990. I took my first sabbatical in 1994--1995, at IBM T. J. Watson Research Center in Yorktown Heights, New York, and at the Centre for Experimental and Constructive Mathematics at Simon Fraser University, Vancouver, British Columbia.
