Li Zhang
I am a Postdoctoral Researcher in the Department of Computer Science and Technology at Tsinghua University, working with Prof. Ju Ren. I received my Ph.D. degree from Beijing University of Posts and Telecommunications (BUPT) in 2025, advised by Prof. Mengwei Xu. I received my Bachelor's degree from Sichuan University in 2019.
My research interests lie in system/software optimization to power emerging mobile/edge applications. I currently work on building mobile agents.
Here is my CV.
