Hi! I am an incoming CS Ph.D. student at UC Berkeley starting Fall 2025. 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.

Previously, I completed my master’s degree at Tsinghua University, where I was advised by Prof. Yu Jiang in WingTecher Lab - Software System Security Assurance Group. I visited the University of Chicago and spent a wonderful summer there, advised by Prof. Grant Ho. I received my bachelor’s degree from Sichuan University.

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.
