About Me

I am currently a second-year Ph.D. candidate in the School of Computer Science at Peking University, advised by Prof. Xin Jin and Prof. Xuanzhe Liu.

My research interests include machine learning systems, distributed storage, and smartNICs, with a recent focus on system for large language models (LLMs).

I received my B.S. degree in computer science from the School of Electronics Engineering and Computer Science (EECS), Peking University in 2023.
