Here is my schedule for Fall 2015.


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, I have slides for a few talks.



 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), Christopher Thornhill (2012), Chun Yin Hui (2013), Neeraj Kashyap (2013), Erik Wallace (2014), Krishna Venkata (2014). Arthur Gershon (2015).

Current Ph. D. students: Kin Wai Chan, WonTae Hwang, Junyan Xu, Zhipeng Lu.


The Putnam Competition is an annual national collegiate math competition. Next year's competition will be held Saturday, December 5, 2015. If you are considering competing, see Hari Bercovici. You may also be interested in his Putnam problem seminar, which meets every Monday at 5:15. 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.
