Silong Yong

I am a Ph.D. student in Robotics Institute, Carnegie Mellon University advised by Prof. Katia Sycara. Previously, I got my Master's degree in Robotics from CMU in 2025 and my Bachelor's degree in Automation from Tsinghua University in 2023.

My research interests lie in 3D computer vision, robotics and graphics. Specifically, I am interested in designing algorithms that model the 3D world in a more natural and sophisticated way, benefitting downstream usages such as robotics and graphics.
