How do I find out the topics for the senior seminars? Are the same seminars offered each semester (year)?

The topics are posted on the department’s Web site on the Senior Seminars page several weeks before the start of the semester. The seminar topics are chosen by the professors, so they will vary as the instructors vary. Professors rarely teach two seminars in the same year, so it is unlikely that the same topic will be offered in both semesters.
