Ze Yang    杨泽

I am a Ph.D. candidate at the University of Toronto and the Vector Institute, advised by Prof. Raquel Urtasun. I am also a Senior Research Scientist at Waabi, focusing on self-driving technology. Before joining Waabi, I was a Research Scientist at Uber ATG. Prior to moving to Toronto, I received a Master's Degree in Computer Science from Peking University, advised by Prof. Liwei Wang.

My research interests focus on the intersection of 3D computer vision, robotics, and machine learning. I'm particularly intersted in neural scene representation, 3D reconstruction and modeling, sensor simulation, and visual perception.

Research

My research goal is to build controllable and realistic digital twins using real-world data, with the purpose of creating immersive virtual environments that facilitate the development and evaluation of robotic systems, such as self-driving vehicles, in a safe, controlled, reactive, and cost-effective manner. Towards this goal, I have delved into various areas over the past few years, such as 3D reconstruction spanning from individual objects to large-scale scene; 3D modeling encompassing both rigid and dynamic content; and closed-loop sensor simulation for camera and LiDAR data. During the earlier stages of my research, I'm interested in learning flexible and structural representation for visual perception. Representative papers are highlighted.
