Hi! I am going to complete my Master’s degree at Tsinghua University this June, where I am advised by Prof. Yu Jiang. During the summer of 2024, I visited the University of Chicago, working under the supervision of Prof. Grant Ho. I received my bachelor’s degree from Sichuan University.

Research Interests: I am interested in the intersection of security, software systems, and data. To understand and mitigate evolving computer security threats, I work to design and develop tools to detect and defend against a wide range of vulnerabilities in software and systems.

A special thank you goes to Yihao for taking this profile photo. In my free time, I am into table tennis, running, science fictions, and livehouse band performance.
