For spring 2018 I'm teaching MATH 215 (Discrete Math) and MATH 412 (Ring Theory). I like visitors. Please feel free to drop by RB 473 at your convenience, though you might call first to make sure I'm in the office (765-285-8640). Links to my mathematical interests and my textbook are in the upper left panel of this page.

Aside from math I enjoy guitar, American and European history, classic horror fiction, and spending time with my family.
