Jiahao Li

avatar I am currently a Senior Machine Learning Engineer at Tesla AI. I received my PhD from TTIC advised by Greg Shakhnarovich. During my PhD I primarily worked on 3D computer vision and generative models, specifically 3D generation and structure from motion. Before TTIC, I received my Master of Computer Science from Washington University in St. Louis advised by Ayan Chakrabarti, and my Bachelor of Mathematics from Sun Yat-sen University. I have interned at Eigen AI, Adobe Resarch and Meta Reality Labs.
