I am a Ph.D. student at Department of Computer Sciences, University of Science and Technology of China from Fall 2018. I am currently advised by Prof. Cheng Li. I obtained my Bachelor’s degree in Computer Sciences (with honors) from Sichuan University in 2018.

My research interests focus on Distributed DNN systems, LLM systems.

Expected to graduate in November 2025, I am actively seeking AI Infrastructure-related positions in the industry, preferably in Shanghai.
