Here is my schedule for Spring 2013.


I am interested in various aspects of algebra, especially:
Here are my papers and preprints. Here they are organized by MSC classification and by coauthor, courtesy of the AMS. Although I prefer chalk, recently I have given a few talks with slides.



 My advisor was Gerd Faltings. He is descended in five steps from Felix Klein, in eight steps from Gauss, and in ten steps from Euler. (My thanks to The Mathematics Genealogy Project for the historical information.)

Former Ph. D students: Michael Movshev (University of Pennsylvania, 1997), Brad Emmons (2003), Bo-Hae Im (2004), Daniel Jordan (2006), Corey Manack (2010), and Christopher Thornhill (2012).

Current Ph. D. students: Neeraj Kashyap, Chun Yin Hui, Arthur Gershon, Erik Wallace, Krishna Venkata.

Tier 3 student: Kin Wai Chan.


The Putnam Competition is an annual national collegiate math competition. Next year's competition will be held Saturday, December 1, 2012. If you are interested in competing, you should contact Marlies Gerber. You may also be interested in taking Math M491, a problem-solving course inspired by the Putnam Competition. Putnam problems and solutions can be found on the web in various places, for instance here.

I served on the Putnam Committee for three years, submitting the following problems:

1996: A4, B3, B5, B6
1997: A3, A4, A5, B2, B4, B5
1998: A3, A6, B4, B5 (actually due to Kamal Khuri-Makdisi), B6
1999: B2

These problems never made prime time, and here are sketches of solutions.
