What lies behind us and what lies before us are tiny matters compared to what lies within us.

Ralph Waldo Emerson

I am actively seeking research internships or funded PhD opportunities that align with my passion and expertise, and a healthy environment where I can work alongside like-minded individuals who value integrity, knowledge, and creativity.

My research interests include computer vision, deep generative models, multimodal large language models, reinforcement learning, and time series analysis.

I obtained my M.Sc. at Sichuan University, Chengdu, China, advised by Professor Yifei Pu. Prior to that, I obtained my B.Eng. degree from Shanghai Normal University, Shanghai, China, and was fortunate to be advised in the fourth year by Professor Yanhua Long.
