Yuchen Lin | 林宇辰

Hi there! I am Yuchen Lin, a third-year undergraduate student at Peking University, majoring in Artificial Intelligence in Zhi Class (an honors program directed by Prof. Baoquan Chen) of EECS School. I am honored to be advised by Prof. Yadong Mu in Wangxuan Institute of Computer Technology, Peking University. I have spent a wonderful semester at School of Computer Science of Carnegie Mellon University as a visiting student. Since then, I have been working closely with Prof. Katerina Fragkiadaki in Machine Learning Department, Carnegie Mellon University.

I am actively looking for PhD opportunities starting in Fall 2026!

Miscellaneous

I love soccer. See how our team lifted the championship trophy 🏆 (a video with audio) in my high school, 2020, and achieved the runner-up 🥈 in the freshman cup of Peking University, 2022!

I am a big fan of Real Madrid. See my friends and I when we watched Madrid win the 2024 Champions League final. Many of them are fans of Barcelona! 😈
