I am a research scientist at Adobe Research. I
completed my Ph.D. from Cornell University in 2021, where I worked with Prof. Kavita Bala. Before that, I received my bachelor degree at Tsinghua University in 2015.
My research interests are at the intersection of computer graphics, computer vision and machine learning, covering physical rendering, neural rendering, 3D reconstruction, 3D generation, relighting, and 3D-aware image/video editing with diffusion models. |
