Changqian Yu - AI Researcher

I am a Senior Research Scientist at Kunlun Tech, leading the team developing cutting-edge large multimodal models, with a focus on Diffusion and VLM technologies. Previously, I served as a Research Scientist at Meituan’s Autonomous Delivery Department, gaining deep insights into real-world AI applications.

I earned my Ph.D. degree from the School of Artificial Intelligence and Automation, Huazhong University of Science and Technology (HUST) in 2021, supervised by Prof. Nong Sang and Prof. Changxin Gao. I was also a visiting Ph.D. student at the Australian Institute for Machine Learning, University of Adelaide, working with Prof. Chunhua Shen.

🏆 During my doctoral studies, I was honored with the Excellent Doctoral Dissertation Award (10 recipients nationwide).

My industry experience includes research internships at Microsoft Research Asia (MSRA) and Megvii (Face++). I collaborated with Dr. Jingdong Wang, Dr. Gang Yu, and Dr. Jian Sun. I was also a key member of the winning team for the COCO & Mapillary Panoptic Segmentation Challenge 2018.

Research Interests: Semantic/Panoptic Segmentation, Trajectory Prediction, and Vision-Language Models.
