Professional Interests

Background

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. After that, I was a Professor in the Mathematics and Statistics Department at Carleton College where I devoted most of my energy in building the statistics program. I am now retired though I am still active in some professional activities. For example, I am an associate editor for the Journal of Statistics and Data Science Education.
