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, and embrace modern civilization.

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

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.
