Intro

I have obtained my Ph.D. degree at HKUST, advised by Prof. Pedro Sander. During the Spring 2019, I was a visiting student to the University of California, San Diego, supervised by Prof. Hao Su. For the autumn 2017, I was a research intern at SenseTime, supervised by Dr. Qiong Yan. Before that, I received my B.S. degree in EE department from Tongji University in 2013.

Since April 2020, I have started at SULab as a postdoctoral researcher, working with Prof. Hao Su.

My research interest includes computer graphics and computer vision, especially in 3D geometry processing, 3D reconstruction. My work covers efficient rendering, multi-view reconstruction, portrait relighting and virtual reality.
