Kwonyoung Ryu
I am a Ph.D. student in the Graduate School of Artificial Intelligence at POSTECH, advised by Prof. Sunghyun Cho and Prof. Jaesik Park. Currently, I am on a research assignment at the Visual & Geometric Intelligence Lab, Seoul National University, with Prof. Jaesik Park. Previously, I received my M.S. degree in Mechanical Engineering at Visual Intelligence Lab, KAIST, where I was advised by Prof. Kuk-Jin Yoon.
My research focuses on robust 3D scene understanding in challenging real-world settings, including 3D perception within multi-view image reconstruction and camera-LiDAR perception for autonomous driving.
