Senior Lecturer in Mathematics

Biography

I specialize in early undergraduate mathematics education, having dedicated my career to it after finishing my Ph.D. in Math in 2009 under the supervision of John Harer. For the past decade, I have taught and supervised Math 105L and 106L, entry-level laboratory calculus courses at Duke. I have edited and created labs for these courses, introducing technological and pedagogical innovations adapted to each year’s students. I have served as a college (pre-major) advisor to dozens of undergraduate students and as major advisor to a few. In 2017, I won Duke’s Advisor of the Year Award, as chosen by the Academic Advising Center based on comments from my advisees. I live in Durham, North Carolina with my partner and young child. My pronouns are he/him/his.

Math 105L: Video Project One of your major bits of work for the semester will be to create a video explaining a mathematical concept, either one from our class, or any other bit of math you find interesting or are curious about.

Math 105L/106L Post-COVID Changes

Executive Summary Over close to two decades of teaching, thinking about teaching, and interacting with students, I have come to the realization that for my particular set of learners, largely students from minoritized and underprivileged backgrounds, the most important component of instruction is the creation of environments in which it is safe to learn mathematics.
