Short Bio

I am a third-year Ph.D. student at Huazhong University of Science and Technology, supervised by Prof. Xin Yang. As first author (including co-first author), I have published 10 papers in top-tier journals and conferences such as T-PAMI, NeurIPS, CVPR, and ICCV. Two of my first-author papers have each received over 300 citations on Google Scholar, and my open-source projects on GitHub have accumulated more than 2,000 stars. I was awarded funding from the National Natural Science Foundation of China PhD Student Research Program and was honored with the title of “Academic Star” at Huazhong University of Science and Technology. I also spent a wonderful time at Shanghai AI Laboratory as a research intern, mentored by Prof. Tianfan Xue. Currently, I am a research intern at Xiaomi EV, focusing on generative world models.
