I am a Research Officer at the Agency for Defense Development, Korea's national defense R&D agency (akin to DARPA) and a First Lieutenant in the Republic of Korea Army. I received my B.S. from DGIST's Interdisciplinary Program, concentrating in Computer Science & Engineering.

Research Interests
My research lies at the intersection of computer vision and robotics, aiming to enable agents to generalize to novel scenarios and execute long-horizon tasks. I am currently developing unified representations that integrate dynamic 3D geometry with open-world semantics. These representations are designed to serve as both predictive world models and spatial memory for policy learning.
My research encompasses three key areas:
1. Spatio-Temporal Scene Modeling (Ongoing)
: Modeling scene dynamics from online observations
2. Vision–Language Representations (ECCV`24)
: Learning open-world semantics that generalize to novel scenarios
3. Implicit Neural Representations (CVPR`23)
: Reconstructing continuous scene representations from sensor data
