I regularly teach calculus courses (MATH 131 / 132) and serve as the calculus coordinator. I also teach graduate courses in mathematics education.
Broadly, I’m interested in research in undergraduate math education — I’d like to know how students learn and how to help them learn better. I have conducted several studies in both calculus and linear algebra.
