About Me

I'm a third-year CS undergrad at Peking University and a member of the Turing Class.

I'm broadly interested in scientifically understanding modern deep learning methods through a combination of theoretical and empirical analysis, with a current focus on optimization of neural networks.

During my undergraduate studies, I worked on theoretical computer science (TCS) and was fortunate to be advised by Shaofeng Jiang, Tongyang Li, Kuan Cheng, and Tianren Liu, among others. I'm also grateful for the guidance from Zhiyuan Li, Kaifeng Lyu, and Lei Wu in deep learning theory.

Currently, I'm visiting the Simons Institute at UC Berkeley.

Experiences

Summer 2024
Research Intern at TTIC, advised by Zhiyuan Li.
2022-2024
Various TCS Research Collaborations, with Shaofeng Jiang on streaming geometric algorithms, Tongyang Li on quantum algorithms, Tianren Liu on security proofs of practical block ciphers, and Kuan Cheng on coding theory. Unfortunately, since transitioning to deep learning theory, I haven't been able to complete many of these projects.
