Hi there and welcome to Planet Quantum.

A little background: My education is at Caltech, MIT, and Stanford.  I've worked at Xerox PARC, Wolfram Research Inc., and University of Waterloo.  Some of you may be familiar with the computer algebra systems Mathematica and Maple.  I worked on both of those systems.  Currently, I am "Principal Software Engineer" at a San Francisco Bay Area computer software startup company which I helped start.
