I've just made web-public the stream on conference announcements from the UC San Diego number theory group Zulip server. (31 Jan 24)

Fast facts (see also my CV)

Teaching for 2024-2025:

See also my past courses.

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. In addition, I am on the program committee for ANTS-XVI.


Current grants: NSF grant DMS-2053473 (sole PI); NSF RTG grant DMS-1502651 (co-PI); UC San Diego, Stefan E. Warschawski Chair; Simons Fellowship in Mathematics. I am also an advisory board member for the UTMOST Project (interactive open-source mathematics textbooks), the Southwest Center for Arithmetic Geometry (including the Arizona Winter School), and the PRiME REU; and an associated scientist of the Simons Collaboration on Arithmetic Geometry, Number Theory and Computation.

Professional societies: American Mathematical Society, Mathematical Association of America (life member), 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, including Math 157, 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, Daniel Kane serves as the UC San Diego Putnam coordinator and teaches the Putnam seminar (Math 96).

Social justice: My work with the BEAM program seeks to create pathways to STEM careers 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 mentor for CalBridge and Math Alliance. I identify as first-gen.
