About me

I'm currently a PhD student in Zhejiang University, advised by Prof. Wenqiao Zhang and Prof. Jun Xiao. Previously, I was also advised by Prof. Jianke Zhu. My research focuses on advancing Visual Understanding, Vision-Language Models and Embodied AI, particularly in:

• Fine-grained spatial-temporal understanding with VLMs: VideoRefer, Osprey
• General VLMs for image/video understanding: VideoLLaMA 3, TokenPacker
• Embodied spatial understanding & reasoning: RynnEC, EOC-Bench, ECBench

Before, I mainly focus on the field of the techniques for object detection, image segmentaion under minimal human supervision, including label-efficient /weakly-supervised /un-supervised approaches.

News

• [2025.9]: Our EOC-Bench is accepted by NeurIPS 2025.
• [2025.8]: We released RynnEC , a video MLLM specifically designed for embodied cognition tasks.
• [2025.6]: We released the EOC-Bench , an object-centric embodied cognition benchmark in dynamic egocentric scenarios.
• [2025.5]: One paper, TokenPacker is accepted by IJCV 2025.
• [2025.4]: Our VideoRefer and VideoRefer-Bench have been discussed and adopted by NVIDIA & UC Berkely in their DAM work.
• [2025.2]: Two papers are accepted by CVPR 2025.
• [2025.2]: We released the VideoRefer-700K dataset on HuggingFace. Please see the VideoRefer Suite for the details.
• [2025.1]: We released VideoLLaMA3, frontier multimodal foundation models for both image and video understanding.
