I joined the Fuzhou University, College of Computer and Data Science, as an Associate Professor in 2025. I received my Ph.D. degree from Fudan University, College of Computer Science and Artificial Intelligence in June 2025, under the supervision of Prof. Bo Yan. Prior to that, I obtained my Bachelor’s degree in Xiamen University, School of Informatics in 2020.

My primary research interests include low-level vision, multimodal learning, semantic segmentation, and AI for Science. I’m looking for master and undergraduate students with strong self-drive and a deep passion for research.

📜 Research Area

1. Low-level Vision, Real-world Super Resolution, Video-Frame Interpolation
2. AIGC, Multimodal, Multi-agent
3. Segmentation, Semi-supervised Learning, AI for Science
