About me

I am a Ph.D. student at KAIST in the Machine Learning and AI (MLAI) Lab, advised by Prof. Sung Ju Hwang. My research interests are in embodied agents, spatially aware intelligence, and robotics. [CV]

Previously, I worked on embodied agents with long-term spatial memory in open-ended environments such as Minecraft, and on injecting spatial structure into transformer architectures (Spatially-Aware Transformer).

Currently, my work focuses on robotics — building sim2real pipelines that bridge physics-based simulators and the real world via video-based world models and vision-language-action (VLA) models, aiming for robust real-world deployment.
