I've been at Wisconsin since the fall of 2005. My field is arithmetic algebraic geometry: my specific interests include rational points on varieties, enumeration of number fields and other arithmetic objects, Galois representations attached to varieties and their fundamental groups, non-abelian Iwasawa theory, pro-p group theory, automorphic forms, stable cohomology of moduli spaces, the complex of curves, Hilbert-Blumenthal abelian varieties, Q-curves, Serre's conjecture, the ABC conjecture, and Diophantine problems related to all of the above. My research here is partially supported by an NSF-CAREER grant and a Sloan Research Fellowship. I am a co-organizer of the Wisconsin number theory seminar. and the organizer of the interdisciplinary "Math And..." seminar.


NEWS: On April 3, 2008, Wisconsin is happy to present the second annual Miniconference on Pro-p Groups and Number Theory. All talks will be held in room B131 of Van Vleck Hall.

The schedule:

1:00: Miklos Abert (U. Chicago): "On the ergodic theory of profinite actions."

2:30: Farshid Hajir (U. Mass): "Asymptotically good families."

3:30: John Wilson (Oxford U) "Characterizations of solubility for finite and linear groups."

If you're interested in visiting, please contact one of the organizers (me or Nigel Boston.)



In Spring 2008, I am teaching Math 844, a graduate course on elliptic curves and modular forms.

On 3-4 November, 2007, Wisconsin hosted the fifth annual Midwest Graduate Student Conference in Number Theory.

On April 7, 2007, Wisconsin hosted a one-day miniconference on "Pro-p groups and pro-p algebras in number theory." Speakers were Mikhail Ershov (U Chicago), Konstantin Ardakov (Cambridge), and Nigel Boston (Wisconsin).

I wrote a novel called The Grasshopper King, which came out in 2003 from Coffee House Press. I also write the "Do The Math" column in Slate, and have written articles on mathematical topics for The New York Times, The Washington Post, The Boston Globe, Wired, Seed, and The Believer.

I used to live in Princeton, NJ; a popular feature of my old web page was How to Eat Dinner in Princeton. Warning: this page is accurate only up to August 2005.

My graduate students: Patrick Rault, Seyfi Türkelli, Guillermo Mantilla-Soler, and Ekin Ozman. If you are considering joining this learned crew, you should read this page.
