With 76 pairings, this was another banner semester for the DRP. We are, as always, grateful for the effort of the mentors and department staff who make all this possible. We couldn’t do it without them.

Now for one of my favorite parts of the program: sharing the completed projects! The pairs who submitted a final paper or do a presentation at our end-of-semester conference are featured below. We hope you find their work entertaining and educational — and that it might serve as a resource if you’re considering starting a DRP project yourself.

The Directed Reading Program continues to go from strength to strength.  Sure, sometimes I forget to order the pizza, and sure, when that happens, sometimes I call La Val’s in a voice that sounds less like a level-headed DRP organizer and more like a disgruntled wombat, but otherwise the program ran very smoothly. We had 67 pairings, more than either of us can remember having in the past, and by all accounts everyone had fun. Special thanks are due to our supervisor Christian Natividad and to Siti Keo and the rest of the math department staff. Applications for the fall program will open in August, and we look forward to seeing you then.

Pairs who submit a final paper or give a final presentation are featured in our wrap-up post at the end of the semester. It is our privilege to share these projects with you. We hope that you’ll enjoy reading them, and perhaps find inspiration for a DRP of your own!

It’s been a fantastic semester for the DRP! We had almost sixty pairings across all areas of mathematics, pure and applied. The program continues to grow and the department continues to support us ably. We’d like to extend a special thank-you to our supervisor Christian Natividad, to Vicky Lee, and to the rest of the staff who make this possible. Applications for the spring will open in January, and we look forward to seeing you then.

Pairs who submit a final paper or give a talk at our end-of-semester conference have the option to be featured in our wrap-up post. It is our privilege to share these projects with you. We hope they will make for interesting reading — and possibly serve as inspiration for DRPs of your own!

The Spring 2023 DRP was a blast.  We paired about 25 undergraduates with mentors, covering a wide variety of topics.  Check out Herman Malik’s presentation on hyperbolic knot theory or Aren Martinian’s write-up on representations of Lie algebras for examples of the sorts of things our students got up to. Other topics included: The Laplace-Runge-Lenz …
