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.
