About Me

I am a 3rd year Ph.D. student at University of Science and Technology of China (USTC), advised by Prof. Linli Xu. Prior to that, I completed my B.Eng in computer science from the same institution in 2023. My primary research interest lies in representation learning and generative mechanisms for more robust, unified, and efficient foundation models.

Aside from my work, I spent a wonderful year with my friends at USTCLUG.
