Li Zhang

I'm a fourth-year Ph.D. student (expected to graduate in Sep. 2025) at School of Computer Science, Beijing University of Posts and Telecommunications (BUPT), advised by Prof. Mengwei Xu. I received my Bachelor's degree in Computer Science from Sichuan University in 2019.

My research interests lie in system/software optimization to power emerging mobile/edge applications. Currently, I am working on building efficient and effective device control agents to automate user daily tasks.

Here is my Curriculum Vitae.
