This year, BEAM has moved its trivia night fundraisers online! They will take place November 7 (Los Angeles) and November 10 (New York). Tickets can be purchased here. (23 Oct 20)

I will continue to hold online office hours on Mondays during fall 2020, plus a social "RTG tea" 4:00-4:30pm PDT/PST. If you wish to schedule a meeting or join tea, email me for the Zoom links. (11 Sep 20)

My online graduate "epicourse" in number theory begins Friday, October 2. See the course web site for more details. (3 Sep 20)

Office hours: throughout fall 2020, I will be holding remote (Zoom) office hours on Monday afternoons; email me to set up an appointment. I also host a social "RTG tea" Mondays 4:00-4:30pm PDT; email me for the link.

Research areas: number theory, arithmetic algebraic geometry. Specialties: p-adic Hodge theory, p-adic/nonarchimedean analytic geometry, p-adic differential equations, algorithms in arithmetic geometry (particularly related to L-functions), interactions between arithmetic geometry and computer science (cryptography, coding theory, etc.). For more, see my questions of interest.

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

Boards of directors: Art of Problem Solving Initiative (this includes governance of Bridge to Enter Advanced Mathematics), board Chair for Pro Mathematica Arte (this includes governance of Budapest Semesters in Mathematics and Budapest Semesters in Mathematics Education). I am also the Vice Chair of the steering committee for the Algorithmic Number Theory Symposium conference series.

Current grants: NSF grant DMS-1802161 (sole PI); NSF RTG grant DMS-1502651 (co-PI); NSF grant DMS-1844206 (custodial 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.

Professional societies: American Mathematical Society, Mathematical Association of America, Association for Women in Mathematics, National Association of Mathematicians.

Software projects: I am an active user and developer of the SageMath open-source computer algebra system. I am a contributor to the LMFDB. Some of my other projects can be found on GitHub.

Other websites: 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.

Social justice: My work with the BEAM program seeks to address opportunity gaps for high-potential K-12 students from underserved backgrounds. I am a proud alum of the PCMI-IAS Workshop on Rehumanizing Mathematics led by the phenomenal Rochelle Gutiérrez. I am a Math Alliance mentor. I self-identify as first-gen.
