Professional Interests


I received my BS in Mathematics from the University of Washington and my PhD in Mathematics from the University of Minnesota. My thesis advisor was Dennis Stanton, and my research area was (algebraic) combinatorics and orthogonal polynomials. I taught for many years in St. Olaf College's Mathematics Department before leaving academia to check out the corporate world. I spent a few years at Insightful Corporation in Seattle (now Tibco) where I learned about S+, a really cool statistics program. Now, I am a Professor in the Mathematics and Statistics Department at Carleton College where I have been especially interested in developing the statistics program.
