I am pursuing a Ph.D. degree at Nanjing University under the supervision of Professor Qing Gu (顾庆) and Assistant Professor Zhiwei Jiang (蒋智威). Additionally, I am currently a visiting Ph.D. student at Singapore Management University (SMU), where I am guided by Associate Professor Qianru Sun and Assistant Professor Jiannan Li, with funding from the China Scholarship Council (CSC).

I have a broad interest in computer vision and deep learning, with a current focus on controllable and consistent generation in AIGC, including audio-driven video generation and text-to-image generation.

From May 2023 to May 2024, I was a research intern at Tencent AI Lab, where I worked under the mentorship of Kuan Tian (田宽) and Jun Zhang (张军), concentrating on research in AIGC.
