I came to St. Norbert College in 1983. I love working with the students here. There are few things as professionally satisfying as watching young minds develop their mathematical skills. When a breakthrough occurs, when a student who is struggling with a math problem suddenly "gets it," then I feel that I've made a difference.
Mathematics is not some soul-less game of performing mindless computations. It is an art, a language, a creative endeavor that allows us to construct and explore new worlds and new ways of doing things. That's why a mathematician can be comfortable talking about Euclidean geometry as well as geometries where parallel lines don't exist. I like teaching all kinds of math, from freshman level pre-calculus through our most advanced topics, but I especially enjoy "pure" proof-based mathematics. The practice of proving a claim, using nothing but definitions, basic axioms, and formal rules of logic, distinguishes mathematics from virtually every other field. Just think: Mathematical properties that were established long ago, such as the Pythagorean Theorem, are still valid today, and what we prove today will be just as valid 1000 years from now.
I get a special kick out of working with students on research projects. Some of the students present their findings at regional or national conferences, others write up their results for our in-house St. Norbert College Journal of Undergraduate Mathematics. Every once in a while, a student and I will co-author something that will appear in a national journal. Here is a piece, written by student Brian Hahn and me, that appeared in the December, 2005, Mathematics Magazine.
Over the years, I have worn a few different hats. For five years (1987-1992) I was the Wisconsin coordinator of American High School Mathematics Examination (AHSME). From 1997 until 2002, I served as the Chair-Elect, Chair, and Past-Chair of the Wisconsin Section of the Mathematical Association of America. Most recently (2002-2007) I served a five-year term as the Associate Dean of SNC's Natural Science Division.
