Biography

I am a year 3 PhD student at The Chinese university of Hong Kong, Shenzhen (CUHKSZ), supervised by Prof. Xiao Li. Before that, I obtained my bachelor degree in computer science from CUHKSZ in 2021.

My research interest lies in understanding modern large-scale deep learning models through its empirical behaviors, including its optimization and generalization properties. Based on thses insights, my objective is to develop effective, explainable, and applicable model. Recently, I am interested in foundation models.
