I teach mathematics and mathematics education to undergraduates and prospective and practicing teachers. My publications (some co-authored with students and teachers) focus on classroom description and appear in research and practitioner journals and books.
I am currently working on transforming a course I developed called Mathematical Modeling With Microsoft Excel into an Online course.
I have enjoyed climbing rocks, mountains and ice, and currently enjoy cross country skiing and skating, hiking and gardening.
