Current Seminars

Crystalline Cohomology (organized with Shizhang Li)

###
Papers

A density result for real hyperelliptic curves (appeared in Comptes rendus). I have recently learned that Andrey Bogatyrev proved this result some years ago. See Theorem 5 and Lemma 1 of this paper (Effective computation of Chebyshev polynomials for several intervals, 1999, Sbornik: Mathematics, vol. 190, no. 11).

Diophantine problems and the p-adic Torelli map (draft, with Akshay Venkatesh)

###
Lecture Notes, etc.

Various expository notes I wrote during my time at Stanford.

Here are some notes from an introductory talk on schemes.

Here are some notes on polynomials on lattices.

Fibonacci Numbers mod p (Stanford SUMO talk, Apr. 10, 2014)

Introduction to Heights (Arithmetic Dynamics talk, Apr. 29, 2014)

In 2013-2014 I ran Stanford's Student Algebraic Geometry Seminar.
