About Me

I am a 3rd-year M.S. candidate of Institute for Network Sciences and Cyberspace at Tsinghua University, where I am fortunate to be advised by Prof. Qi Li. My research focuses on wireless protocol optimization and robustness.

Previously, I received a B.E. degree from the Department of Electronic Engineering at Tsinghua University.

I served as a volunteer middle school teacher in Xinjiang, Tibet, Shanxi, and Fujian.
