My research interests are in geometry, especially Riemannian geometry, dynamical systems, and variational problems. At present my work concerns finite- and infinite-dimensional integrable Hamiltonian systems arising from geometric problems.

Check for current information on my courses
and my office hours.
My office is Yost 307.

My current teaching interests are algebra, geometry, number theory and cryptology,
the mathematics of secure communications. 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 have worked with the Cleveland Collaborative for Mathematics Education to help students and teachers in the Cleveland Schools.

Here is a link to a math education website.

The Mathematical Association of America maintains a student web-site for mathematics majors and other interested students, and a Career Resource Center. Another link of possible interest to students looking for career advice is MoneyGeek.

Some other sites to explore from here:

- American Mathematical Society Home Page.
- National Public Radio (including This American Life and Diane Rehm)
- Other Math Servers (USA here)
- Cryptology Links
- Biographies of Women Mathematicians
