Hello! I'm a 3rd-year math Ph.D. student at the University of Pennsylvania. My research interest lies in harmonic analysis and related fields. My advisors are Yumeng Ou and Philip T. Gressman.

I've been working on (weighted) Fourier restriction, especially in higher-codimensional cases. I'm also interested in the interaction between geometric (maximal) averaging operators, incidence geometry, and geometric measure theory.

I received my B.S. in Mathematics in 2023 at Peking University.
