About me

I graduated from Columbia University in May 2025, where I was fortunate to be advised by Prof. Omri Weinstein and Prof. Alexandr Andoni.

In Fall 2025, I will visit the Simons Institute at UC Berkeley for the Complexity and Linear Algebra program.

Beginning in Janurary 2026, I will join the Institute for Theoretical Studies in ETH Zurich as a junior fellow.

My research has focused on developing data structure frameworks to speed up conic programming. I am also broadly interested in other problems in numerical linear algebra and data structures.

Experiences

Previously I obtained my bachelor's degree from Yao class at Tsinghua University, where I worked with Prof. Ran Duan and Prof. Jian Li.

In Spring 2018, I exchanged to Aarhus University where I worked with Prof. Kasper Green Larsen.

In Fall 2023, I visited the Simons Institute at UC Berkeley, where I participated as a research fellow in the Data Structures and Optimization for Fast Algorithms program.
