Cheng Zhang

I am a research scientist at Meta Reality Labs. I received my Ph.D. degree from University of California Irvine in 2022, advised by Prof. Shuang Zhao. During my Ph.D. studies, I was awarded the 2021 Facebook Fellowship. Before that, I obtained my B.E. in Electrical Engineering from BJUT (2011-2015) and my M.S. in Computer Science from Columbia University (2015-2017).

My research focuses on physics-based rendering and its inverse problems (i.e., analysis by synthesis) centered around the inference of geometric and material properties from physical measurements (e.g., photographs, depth data). To develop a general solution to various inverse rendering problems, I have been working actively on the topic of physics-based differentiable rendering.
