Ziyi Zhang 张梓毅 I am a fourth year PhD student in the Realistic Graphics Lab at EPFL, adviced by Prof. Wenzel Jakob. I'm interested in physical light transport simulation and its differentiation. During my PhD, I have had the opportunity to work as an intern with NVIDIA and Google. Before that, I obtained my bachelor's degree from NYU where I had the privilege of working with Prof. Daniele Panozzo. Email / Google Scholar / Github / Bluesky |
