Ziyi Zhang 张梓毅

I am a fourth year PhD student in the Realistic Graphics Lab at EPFL, supervised by Prof. Wenzel Jakob. Before that, I obtained my bachelor's degree from NYU. I'm interested in computer graphics. My current research is about designing robust algorithms for physically based differentiable rendering.
