Changyang Li

Ph.D. Candidate @ George Mason University. I am looking for research positions.


I work as a Graduate Research Assistant at the Design Computing and Extended Reality Group, advised by Prof. Lap-Fai Yu. Before that, I received my MS degree in Computer Science at the University of Virginia, and BS degree in Computer Science at Beijing Institute of Technology.

My research interests include graphics, mixed reality, vision, human-computer interaction, and computational design. Specifically, I study generative 3D content (virtual human activities and environments, NeRFs) for facilitating AR, and scene-adaptive AR/VR + HCI.
