News (see also past news)
The call for papers for ANTS XVI is open; it closes January 19, 2024. (30 Oct 23)
Fast facts (see also my CV)
Teaching for 2023-2024: None. I will be visiting IAS for most of the year, participating in the special year on p-adic geometry. I will continue to hold office hours for PhD students over Zoom; email me to schedule.
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.
Governance:
- Art of Problem Solving Initiative, member of board of directors (this includes governance of Bridge to Enter Advanced Mathematics).
- Pro Mathematica Arte, chair of board of directors (this includes governance of Budapest Semesters in Mathematics and Budapest Semesters in Mathematics Education).
- American Mathematical Society, on AMS Council, Committee on Publications, and Executive Committee of the AMS Council.
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 UCSD 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.
Tips for reaching me by email
In case you send me an email and get no response, the following tips may help you diagnose the issue.- I typically process my email as a last-in-first-out (LIFO) queue, with a postponement for messages that cannot be answered quickly. A single message containing multiple issues may take significantly longer to elicit a response than multiple messages containing single issues.
- At the moment, I do not have time to review grant proposals or to write full referee reports for articles. In limited cases I may be able to provide quick evaluations for papers that are sufficiently close to my expertise; I am currently prioritizing requests for "doubly-anonymous" opinions, i.e., those for which the names of the authors have been suppressed.
-
My direct supervision of students is typically limited to students at UCSD, and takes the following forms. (Exceptions to "UCSD student only" include participants of programs affiliated with UCSD, the UC system, or the Math Alliance.)
- For undergraduates: faculty coordinator for an off-campus internship (Math 197; generally for students who took Math 157), reading course/honors thesis (Math 199/199H).
- For graduate students: reading course/PhD thesis (Math 299), dissertation committee (including as an external member). In rare cases I may also serve as faculty coordinator for an off-campus internship (Math 297).
- Regarding recommendation letters, see my separate page.
- UCSD runs a hyperagressive spam filter which I am not able to completely circumvent, leading to silent loss of some messages or attachments. It might help to change the sending address. In case of emergency, try voicemail (or my non-UCSD email address or cell phone number if you have one of those).
