### Summer, 2007

- Research Experiences for Undergraduates, a program sponsored by the National Science Foundation. I didn’t run a research project this summer. Instead, I ran the program as a whole.

### Spring, 2007

### Summer, 2006

- Research Experiences for Undergraduates, a program sponsored by the National Science Foundation. Together with Dr. Palagallo, I supervised a project on
*Self-similar tilings of nilpotent Lie groups*.

### Spring, 2006

- Linear Algebra (MAT223S) at the University of Toronto.
- Master’s thesis research with Mike Garlow, co-advised by Ethel Wheland:
*An elementary classification of the groups of order 81*. We later generalized this to handle the groups of order*p*for^{4 }*p*an odd prime.

### Summer, 2005

- Research Experiences for Undergraduates, a program sponsored by the National Science Foundation. Together with Dr. Price, I supervised a project on
*Generalized Fibonacci-Lucas pairs*. Together with Dr. Levin (in the history department), I supervised a project on*Reading encrypted diplomatic correspondence*. The results of this latter project have now been published.

### Spring, 2005

*3450:412/512 Abstract Algebra II.*We continued with the study of groups, rings, and fields. Our aim was to solve some of the great mathematical problems of antiquity. You can read the course rules and course plan (which lists most of the homework assignments).

### Fall, 2004

*3450:135 Excursions in Mathematics*. (This course was previously called*Mathematics for Liberal Arts*.) Need to take a math course? This one is different from any that you have ever taken before. Check out the course materials to see if it is right for you. (The textbook also has a web page of its own.)*3450:411/511 Abstract Algebra I.*We studied what’s been going on behind the scenes.

### Spring, 2004

*3450:135 Mathematics for Liberal Arts*. This course has since been renamed:*Excursions in Mathematics*.*3450:412/512 Abstract Algebra II.*We continued with the study of groups, rings, and fields. Our aim was to solve some of the great mathematical problems of antiquity. You can read the course rules, and a draft of the course plan (which lists most of the homework assignments).*Graduate Seminar*. This was team-taught with Dr. Riedl. He introduced his recent work on ascending central series of p-groups, and then made you do some computations of your own. Then I covered the basic theory of modules, which simultaneously generalizes several theories that you have already seen. You then applied the theory to one of the following: representation theory, linear algebra, the classification of finitely-generated abelian groups, or “abstract nonsense” (a technical term that I did not make up).
