Hyunjoon Lee

I am an integrated MS/PhD student at VGI Lab (Visual and Geometric Intelligence Lab) at Seoul National University, where I am advised by Prof. Jaesik Park.

My research interests lie at the intersection of robotics and 3D vision. I am particularly interested in how we can leverage rich scene information to enhance robot manipulation capabilities in complex environments.

Real2Sim VLA

A VLA model was fine-tuned on real-world scene data, and the corresponding scene was reconstructed with 2DGS and converted into a USD-compatible mesh for integration with Isaac Sim. This enables the VLA to run in a photorealistic Real2Sim environment for post-training and diverse scene-level evaluation.
