I am 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 B.Eng. in Computer Science and Technology from Sichuan University, where I was advised by Prof. Qijun Zhao.
My research interests primarily include:
- Multimodal LLMs: efficient inference and post-training for MLLMs.
- Medical Multimodal AI: multimodal reasoning and few-shot learning for medical image understanding.
News
Released our preprint on few-shot medical image segmentation benchmarking.
Released Fundus-R1, a fundus-reading MLLM trained with knowledge-aware reasoning on public data.
Our work on dynamic memorization and exploration for small VLMs appears at ICLR 2026.
Started my Ph.D. at Renmin University of China under the supervision of Prof. Xirong Li.
Graduated from Sichuan University and was honored as an Outstanding Graduate of Sichuan Province.
Our paper on text-based person search was accepted to ICME 2025.
Started a research internship at Baidu, focusing on large-scale model data.
