Here is my schedule for Spring 2017.


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).

The Putnam Competition is an annual national collegiate math competition. This year's competition will be held Saturday, December 2, 2017. For more information, see Hari Bercovici. 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.
