Biography

I am a first-year Ph.D. student in Information Engineering at Shanghai Jiao Tong University (SJTU), advised by Prof. Jia Wang. Now I intern at BlueImage Lab, vivo, collaborating with Dr. Tianyi Zheng. I received my B.Eng. and B.S. dual degrees from Shanghai Jiao Tong University in 2025. I conducted research under the supervision of Quanshi Zhang from 2022 to 2024.
