Delio Vicini
Senior Research Scientist at Google
Zurich, Zurich, Switzerland
Summary
🤩
Rockstar🎓
Top SchoolDelio Vicini is a Senior Research Scientist based in Zurich with 12 years of experience specializing in physically-based differentiable rendering and inverse light-transport problems. He has driven improvements in both accuracy and efficiency of renderers, contributing substantively to the widely used Mitsuba 2 and Mitsuba 3 engines—especially volumetric path tracing, numerical robustness, and core pipeline features. At Google he bridges rigorous academic research with production-grade systems, building on a PhD from EPFL and internships at Facebook Reality Labs and Disney that focused on novel volume models and denoising. His work uniquely combines principled light-transport differentiation with practical speedups—such as leveraging generative models and gradient-domain techniques—to make inverse rendering tractable.
