Changyang Li

I am a Research Scientist at Goertek Alpha Labs. I received my Ph.D. in Computer Science from George Mason University, where I was advised by Prof. Lap-Fai Yu. Before that, I received my M.S. in Computer Science from the University of Virginia and my B.S. in Computer Science from the Beijing Institute of Technology.

My research interests include computer vision, computer graphics, extended reality, and human–computer interaction. Specifically, I study scene understanding and perception, generative 3D content, and scene-adaptive and interactive AR/VR.
