Guocheng Gordon Qian

Welcome! I am a research scientist at Snap Research working on Personalized Generative AI. I earned my Ph.D. in Computer Science from KAUST, where I was fortunate to be advised by Prof. Bernard Ghanem. Prior to that, I received my B.Eng degree from Xi'an Jiaotong University (XJTU), China with the university’s highest undergraduate honor. My primary research interests lie in computer vision and generative models. My representative work includes PointNeXt (NeurIPS), Magic123 (ICLR) and Omni-ID (CVPR'25).
If you are interested in working in generative models (image, video, MLLM, agents) with us, please drop me a message through guocheng.qian [at] outlook.com
