Teaching

Fall 2020

This semester, I'm teaching Math 1013 (Trigonometry), Math 1101 (Calculus I), and Math 3111 (Linear Algebra). Students can find their course info on Canvas.

Research

Students occasionally ask me about my research. Here is an accessible, relatively nontechnical explanation: Research Description (pdf).
