  • Posted on 09/03/2009 by Loretta
  1. Many students have been asking me about the course schedule. At the moment, the list of presenters is last year's students, as we are waiting a few more days to see if any additional students will add/drop this course. Dr. Rizzo and I will update the list with the enrolled students by the middle of next week (around 9/10 or 9/11).
  2. The presentation topics and associated papers will be assigned to you. Traditionally, we do this alphabetically.
