Qiyu Dai | 戴启宇

I am a first-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

My research aims to develop Extended Reality (XR) systems that perceives the physical world and creates immersive experiences. Currently, I focus on integrating 3D/4D reconstruction, physics simulation, and generative models to build World Simulators enabling interactive digital twins. I am also interested in neural rendering, egocentric scene understanding, and lightweight depth sensing.
