About me

I'm a fourth-year undergraduate student (2022.9 - Present) in Turing Class, Chu Kochen Honors College, Zhejiang University. I am also an incoming PhD student at SphereLab, the Chinese University of Hong Kong, advised by Prof. Weiyang Liu. During my undergraduate studies, I have had the privilege of working with Prof. Yulun Zhang and Prof. Huan Wang.

My current research interests focus on empirical and theoritical understanding of deep learning models. Specifically, I am interested in developing principled approaches that are scalable and generalizable across tasks in natural language processing and computer vision. Recently, I have been exploring parameter-efficient fine-tuning, learning dynamics and optimization.
