I am the tenure-track Assistant Professor of College of AI at Tsinghua University since 2025. Before that, I obtained my PhD degree from Peking University in 2025, supervised by Prof. Zhi Jin and Prof. Ge Li.
Now, I lead the Tsinghua AI Agent Group and work closely with Prof. Shi-Min Hu. Our group focuses on trustworthy agents, safe agents, and software engineering. Our group maintains close cooperation with companies such as Tencent, Alibaba, and Ant Group. Welcome to contact me if you are interested in collaboration.
I am looking for highly-motivated research interns, master students, PhD students and Postdoctoral researchers to join my group. Feel free to email me with your resume attached.
