Shengqu Cai

I am a CS PhD student at Stanford University and a research scientist intern at Adobe Research. My research is partly supported by a Stanford School of Engineering Fellowship.
Previously, I was a CS master student at ETH Zürich supervised by Prof. Luc Van Gool.
In 2022, I spent a wonderful half a year visiting Stanford University at the Computational Imaging Lab led by Prof. Gordon Wetzstein, working on scene extrapolation with Eric Chan.
Before this, I obtained my Bachelor degree in Computer Science with first honour from King's College London in United Kingdom, working on unsupervised learning.

I am interested in solving graphics or inverse graphics tasks that are fundamentally ill-posed via traditional methods, slay the unslayable. I have been working primarily around neural rendering, including but not limited to generative models, inverse rendering, unsupervised learning, GAN inversion, scene representations, visual content creation, etc.
