🎓 About Me

I am a Lecturer at Yunnan Normal University. I obtained my Ph.D. degree in Information and Communication Engineering from Southwest Jiaotong University in 2025, where I was supervised by Prof. Turgay Celik and Prof. Heng-Chao Li. From Feb 2023 to Dec 2024, I was a Visiting Student at A*STAR in Singapore, supervised by Dr. Xun Xu and Dr. Chuan-Sheng Foo. My research focuses on remote sensing image analysis and computer vision, with specific interests in few-shot/semi-supervised object detection, domain adaptation, and weakly-supervised segmentation.
