About

I am a fifth year graduate student in mathematics at Princeton University, advised by Peter Sarnak. Previously, I completed my bachelor's degree at Stanford University, advised by Kannan Soundararajan. My research is in analytic number theory, especially in prime values of polynomials and point-counting on varieties. I am also interested in arithmetic statistics and cryptography. I am currently funded by the NSF GRFP under Grant No. DGE-2039656.

Teaching and Miscellaneous

• (Teaching at Princeton) In Summer 2022, Summer 2023, and Spring 2024, I was the teaching assistant for Mat 202 (Linear Algebra). In Fall 2023, I was a teaching assistant for Mat 103 (Calculus I).
• (Miscellaneous at Princeton) In 2021-2022, I organized a preparatory learning seminar for the 2022-2023 IAS Special Year with Noah Kravitz and Giorgos Kotsovolis. I am a current member of the math department's graduate student committee and an organizer of the Noetherian Ring, Princeton's group for women and gender minorities in math.
• (Teaching at Stanford) In Spring 2019 and Spring 2020, I was the teaching assistant for CS 355 (Advanced Topics in Cryptography).
• (Miscellaneous at Stanford) In 2018-2019, I was the President of the SUMO (Stanford's student math organization). In 2019-2020, I helped inaugurate the Stanford math department's peer advising program.
