I'm a professor in the Department of Mathematics at Simon Fraser University, where I've worked since 2003.

Before moving to the magical city of Vancouver, I spent 14 years
at Hewlett Packard Research Labs in the United Kingdom, where I
used mathematics to solve practical problems in digital communications.
