My career has been as a mathematician, principally as a college professor at a smaller liberal arts college, the University of Puget Sound. I am the author of an early open source textbook, A First Course in Linear Algebra. This has been an experiment in the possibilities afforded by fast and prevalent networks, open licenses, and new economic models (the economics of abundance, not scarcity).

I received my PhD in mathematics from the University of Illinois at Urbana-Champaign in 1984, along with a Masters in Statistics. My undergraduate education included calculus at the University of Washington in the evenings of my last year of high school, and then three years at Santa Clara University and the excellent mathematics department there. Since 1984 I have taught in the University of Puget Sound’s mathematics department, excepting sabbatical trips to the University of the West Indies, the University of Western Australia and the African Institute of Mathematics.

For about 15 years after my PhD, I pursued a traditional research program in algebraic graph theory and related areas of combinatorics. Three years as department chair, a decision to write a textbook, two years as a faculty liaison to a $60 million science building remodeling project and general excitement about the open source mathematics software Sage, have taken me in new directions the past 10 years. Hopefully this blog will chronicle that continued progression.

My wife has a career as a veterinarian and I have two adult sons, born in 1992 and 1994. I try to swim for regular exercise and cycle for more entertaining recreation. I enjoy hacking with/on open source software, Sage and digital photography. Travel is also a big personal interest.

If you want to learn more, I have a professional website and a poorly-maintained personal website.

Hi Rob:

Cool blog. Can you add an rss feed tab to make it easier to follow?

Thanks, David. Could you give it a test? I think I now have a button and a link that will allow you to subscribe to the feed.

This is first prize, blue ribbon maetairl you have written here. I haven’t had the pleasure of reading such interesting content in quite some time.
