About me

Hi! I’m Yuchuan Deng, a Ph.D. student at the AI & Media Computing Lab (AIMC Lab), Renmin University of China (RUC), supervised by Prof. Xirong Li.

I received my Bachelor of Engineering in Computer Science and Technology from the College of Computer Science, Sichuan University (SCU), advised by Prof. Qijun Zhao.

My research interests include resource-efficient multimodal large language models, ophthalmology-oriented multimodal LLMs, and multimodal video retrieval.
