### Who Am I?

I am a research associate at Simon Fraser University and a member of the
Computer Algebra Group
at the CECM.

My expertise is
high performance parallel programming, sparse polynomials, linear algebra, and Groebner bases.

I live in Abbotsford, British Columbia, Canada.

### Sparse Distributed Multivariate Polynomials

Sdmp is a state of the art library for sparse multivariate polynomial arithmetic.
It is used by the Maple computer algebra system.

This is joint work with Michael Monagan at Simon Fraser University.
It is sponsored by the MITACS NCE and NSERC of Canada, and Maplesoft.

**Current release:** Maple 18

### Recent Slides

Sparse Polynomials in Maple given at the University of Sydney.
