About me Research Publications Students Teaching Talks Links

My research area is known as computer algebra. I have worked on the Maple project since 1983. Maple is one of several computer algebra systems. It was developed at the University of Waterloo in the 1980s. I can supervise graduate students at Simon Fraser University who are interested in pursuing a graduate degree in computer algebra at the Ph.D. and Masters' level. Students need to have an interest in both mathematics and computer science. Students should contact me directly by Email. Before you send me an application, please find out what computer algebra is, and in your letter, say why you are interested in doing computer algebra.

For details of my current research projects, please see my recent publications.
