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 graphics, computer vision, mixed reality, and human–computer interaction. Specifically, I study scene understanding and perception, generative modeling of human activities and environments, and scene-adaptive AR/VR with HCI.
