About Me

I am a senior undergraduate student at ACM Honors Class, Shanghai Jiao Tong University majoring in Computer Science.

Now I am a visiting student at MIT HAN Lab advised by Prof. Song Han. During my junior year, I am very fortunate to work with Prof. Yu Feng and Prof. Guohao Dai.

I am passionate about efficient machine learning, which involves designing algorithms, systems and hardware for machine learning applications. My long term goal is bringing efficient foundation models for everyone, as well as advancing their capability and scalability.

In the future, I plan to pursue a Ph.D. in Computer Science, starting in Fall 2026. If you are interested in my research, please feel free to contact me.

💡 Let's see our recent work: [NeurIPS'25] Radial Attention, featuring O(nlogn) Sparse Attention for training/inference acceleration of video diffusion models! Feel free to try it with the official implementation or on the state-of-the-art WanVideo inference engine.
