About me
|
I'm a principal research scientist in LightSpeed Studios, Tencent America. Previously, I was a postdoctoral associate in the Computational Design & Fabrication Group under the guidance of Prof. Wojciech Matusik at MIT CSAIL. I received my PhD degree in Computer Science from University of Utah in 2019, advised by Prof. Cem Yuksel. My research interests are computer graphics, including modeling, rendering, simulation, and fabrication.
