I am a 3rd-year Ph.D. student at the College of Computing and Data Science, Nanyang Technological University, Singapre, supervised by Prof. Bo An. Previously, I obtained my B.Sc. of Artificial Intelligence from Nanjing University in 2022. In my undergraduate study, I worked with Prof. Yang Yu at LAMDA. I also interned at the MMLab of the Chinese University of Hong Kong with Prof. Bolei Zhou, Kuaishou Technology with Dr. Qingpeng Cai, Kunlun 2050 Research with Prof. Shuicheng Yan and TikTok with Dr. Qian Liu.
I study safe, robust, and generalizable decision-making algorithms and their applications in real-world problems, such as large language models, GUI navigation, video games, autonomous driving, robotics locomotion, and recommendation systems.
I am on the 2026 job market. Feel free to reach out!
