Hello! I am a third-year graduate student in the MIT Mathematics Department, where I am advised by Professor Michel X. Goemans. Before that, I obtained my B.Sc. in Computer Science and Mathematics (Combined Honours) with Distinction at the University of British Columbia, where I was very fortunate to be advised by Professor F. Bruce Shepherd. Even before that, I attended Shaoxing No. 1 High School, where I participated a lot in competitive programming.

My research interests include algorithms, combinatorics and optimization, in particular designing discrete algorithms and analyzing discrete structures. I am also broadly interested in theoretical computer science, operations research and graph theory.

While not doing mathematics, I enjoy hiking, kayaking and skiing. I am peak-bagging the “NH 48” list of 4000 footers in New Hampshire.

You can find me at [first-name] [at] mit [dot] edu.


Apr 11, 2024 I will be back in Vancouver from May 18 to May 23! Let me know if you are also around. One or two talks in UBC CS are being scheduled. 🇨🇦
Apr 11, 2024 I will be in Miami on April 12 to attend the Citadel Securities PhD Summit. Stop by my poster (on my work with Alan) if you are also there! 🏝
Oct 16, 2023 I hiked the Pemi loop with Shutao! ⛰
Oct 11, 2023 Tomorrow (October 12) in 2-132, I will give a talk titled Fantastic Spanning Trees in Planar Graphs and Where to Find Them, based on my joint work with my RSI student Alan, at the Simple Person’s Applied Math Seminar (SPAMS). Food from 醉杭州 (including 酒酿圆子) will be provided! 🥘
Aug 6, 2023 I am flying back to China after 4 years and 3 months! I will land on August 11. Let me know if you want to grab coffee/lunch/dinner together. 🛬
