Fujun Luan

I am a research scientist at Adobe Research. I received my Ph.D. from Cornell University in 2021, under the supervision of Prof. Kavita Bala. During Ph.D. study, I was awarded the 2017 Adobe Research Fellowship. Before that, I obtained my bachelor degree from Tsinghua University in 2015, advised by Prof. Kun Xu.

My research interests include various topics in computer graphics, with a recent focus on inverse graphics, differentiable rendering, and neural rendering.
