Biography

I am a Ph.D. student in School of Computer Science at Peking University, advised by Prof. Xiaolin Wang and Prof. Tong Yang. My research interests include inference optimization in LLM, quantization algorithms for large models, and sketching algorithms in data streams. I also work as a research intern at Baichuan Inc. Before I start my Ph.D. degree, I received my bachelor degree in Computer Science and Mathematics at Peking University in 2023.
