👋 Welcome!

My name is Di Wang (王迪), a first-year Master's student at Tsinghua University, supervised by Prof. Han Qiu. My research focuses on LLM content safety/security and AI agents. I believe research should have real-world impact. Beyond papers, I enjoy building open-source projects that turn ideas into practical tools. Check out my GitHub for more.
