I am a fourth-year Ph.D. student in Mathematics at Caltech. My advisor is Elena Mantovan.

My research interests include Shimura varieties, the Langlands program, arithmetic geometry, and post-quantum cryptography.

Here is my CV (updated September 2019).


Papers

On the Hecke Orbit Conjecture for PEL type Shimura varieties. In preparation.

Abstract: For a prime p, the Hecke orbit conjecture asserts that every prime-to-p Hecke orbit in a PEL type Shimura variety is dense in the central leaf containing it. We prove that the conjecture holds for irreducible components of Newton strata which contain hypersymmetric points.

Miscellaneous

Introduction to SIKE. This my final project report for CS152 Introduction to Cryptography in Fall 2018. It gives a brief introduction to the Supersingular Isogeny Key Encapsulation suite submitted to the NIST standardization process on post-quantum cryptography by Jao et al.

I'm a certified Mental Health First Aider by Mental Health First Aid USA. Feel free to reach out to me if you are experiencing a mental health or substance use challenge. I'm not a therapist, but I can provide initial help until appropriate professional resources are available.

During the last two years of my undergraduate studies, I translated Brian P. Copenhaver's English translation of the Hermetica into Chinese. My translation was published in July 2019 as a volume in the "经典与解释"(Hermes: Classici et commentarii) book series.

Here's a commentary (in Chinese) I wrote for the first ever Chinese translation of the prose Edda, where I give some background on the Eddas and explain Old Norse poetic forms via two examples.
