I am a 3rd-year Ph.D. student at the School of Computer Science and Engineering, 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, and Kunlun 2050 Research with Prof. Shuicheng Yan.

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.
