About me
I am a research scientist at NVIDIA. I received my Ph.D. degree from University of California San Diego in 2020, advised by Prof. Ravi Ramamoorthi. During my Ph.D. career, I was awarded the 2019 NVIDIA Graduate Fellowship. Before that, I obtained my bachelor degree from Tsinghua University in 2015.
My research focus is on physically based rendering, aiming at efficient modeling and simulation of complex visual appearance. I am also interested in differentiable light transport and inverse rendering problems.
