Or Litany – 3D Computer Vision & Generative AI Researcher at NVIDIA and Technion

Or Litany

I'm a Senior Research Scientist at NVIDIA Research and an Assistant Professor at the Technion, specializing in 3D computer vision and generative AI. I'm honored to be a 2023 Azrieli Faculty Fellow and a Taub Fellow. Previously, I conducted postdoctoral research at Stanford University under Prof. Leonidas Guibas, and at FAIR, hosted by Prof. Jitendra Malik. My PhD is from Tel-Aviv University, advised by Prof. Alex Bronstein. My B.Sc. in Physics and Mathematics is from the Hebrew University.
