• I am currently serving as Associate Department Head for Curriculum

• Last semester, I taught Math 300 (Introduction to Mathemtical Thinking) using the book "Introduction to Mathematical Structures and Proofs" by Larry Gerstein.  In 2025-6, I'll be teaching Math 611-2, the graduate sequence in abstract algebra.  We'll use Dummit and Foote's book.
