At the moment, I am generally unable to accept requests to review manuscripts or grant proposals, or to write post-tenure recommendation letters.

Fast facts (see also my CV)

Current teaching (see also my past courses):

I was not teaching during 2018-2019, having been a Visiting Professor at the Institute for Advanced Study in Princeton.

Office hours: by appointment (email) during fall 2019. If you don't have an appointment, you are most likely to find me in the office on Mondays or Wednesdays after 2pm, but appointments take precedence over walk-ins.

Research areas: number theory, arithmetic algebraic geometry. Specialties: p-adic analytic methods in arithmetic geometry, p-adic Hodge theory, p-adic differential equations, algorithms in arithmetic geometry, interactions between arithmetic geometry and computer science.

Editorial boards: Nagoya Mathematical Journal, L-Functions and Modular Forms Database.

Boards of directors: Art of Problem Solving Initiative (this includes governance of BEAM: Bridge to Enter Advanced Mathematics), Pro Mathematica Arte (this includes governance of Budapest Semesters in Mathematics and Budapest Semesters in Mathematics Education).

Current grants: NSF grant DMS-1802161 (sole PI); NSF RTG grant DMS-1502651 (co-PI). I am also an advisory board member for the UTMOST Project (interactive open-source mathematics textbooks), an advisory board member for the Southwest Center for Arithmetic Geometry (including the Arizona Winter School), and an associated scientist of the Simons Collaboration on Arithmetic Geometry, Number Theory and Computation.

Other: I am an active user and developer of the Sage open-source computer algebra system, both as a standalone application and via the CoCalc (formerly SageMathCloud) web portal. I am a curator for MathMeetings, from which my conference list in arithmetic geometry is now derived. I maintain the Putnam Archive within this website; however, the UCSD Putnam coordinator is Daniel Kane.

Fine print

Beware that my response time to non-urgent emails tends to vary exponentially with the time needed to compose the response. I recommend separating distinct issues into separate messages, so that I can answer them individually. I have also had some issues with emails disappearing into my university's filtering system; in case of emergency, try voicemail (or my non-UCSD email address if you have it).
