Qiyu Dai 戴启宇

I am a second-year Ph.D Student in Intelligent Science and Technology at Peking University, supervised by Prof. Baoquan Chen. Before that, I received my M.Eng. from Peking University, supervised by Prof. He Wang and Prof. Qi Jing, and Bachelor from Wuhan University. I am also privileged to work closely with Prof. Wenzheng Chen, Prof. Mengyu Chu, Prof. Pengshuai Wang at Peking University.

Research

I work at the intersection of 3D Computer Vision and Computer Graphics. My goal is to develop intelligent systems that can perceive, understand, and generate dynamic, physical 3D worlds, facilitating next-generation AR/VR and AI glasses. Currently, I am working towards building controllable, generative world simulators that enable realistic interaction with humans. I am also interested in 3D/4D reconstruction and generation, neural rendering, and spatial understanding.
