I am a third-year Ph.D. student at MMLab, CUHK, advised by Prof. Dahua Lin. My research interests lie in broad area of MLSys, especially efficient large scale DNN training and inference. Before joining CUHK, I received my Bachelor’s degree in Computer Science from University of Chinese Academy of Sciences, advised by Prof. Shiguang Shan.

I will be on the job market for 2025. Please feel free to reach out if you have openings in industry or academia.

My detailed CV can be found here.
