I am currently a PhD student in the Department of Computer Science and Engineering at The Chinese University of Hong Kong, advised by Prof. Hong Xu. My research interests lie in AI infrastructure and large-scale distributed training.

I am also a research intern with the Infrastructure team at ByteDance Seed. Previously, I was fortunate to be advised by Prof. Xingda Wei and Prof. Haibo Chen at the Institute of Parallel and Distributed Systems (IPADS), Shanghai Jiao Tong University.

I received my bachelor’s degree from the School of Computer Science and Technology at Huazhong University of Science and Technology.
