My current teaching interests are number theory and cryptology, the mathematics of secure communications. I teach a course in number theory, MATH 303, in the fall semester, and a course in mathematical cryptology, MATH 408, in the spring semester. Please contact me for further information.

Geometry: Plane and Fancy is a tour of aspects of geometry that students are unlikely to have seen in a high school geometry course.
I am interested in educational issues in mathematics, particularly concerning the reform movement in K-12 mathematics education and at the college level, and the use of new technologies. I would like to see greater interaction between research mathematicians at places such as CWRU and teachers of mathematics. I am working with the Cleveland Collaborative for Mathematics Education to help students and teachers in the Cleveland Schools.
