Hi there! This is Yiyuan, a first-year Ph.D. student at 🍌UC Santa Cruz.

I have a broad interest in theoretical computer science, especially in approximation algorithms for combinatorial problems. Currently, I am fortunate to be advised by Prof. Vaggos Chatziafratis.

Before coming to UCSC, I graduated from Beijing Jiaotong University.

I play in coding competitions in my free time. See my LeetCode and Codeforces profiles! Some of my other interests include speedcubing and skiing.
