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.
My research encompasses three key areas:
1. Spatiotemporal Scene Representations (Ongoing)
: Modeling scene dynamics from online observations
2. Vision-Language Representations [ECCV 2024]
: Learning open-world semantic representations that enable generalization
3. Implicit Neural Representations [CVPR 2023]
: Reconstructing continuous scene representations from sensor data

Ongoing Projects
Active
4D Neural Implicit Mapping
We build dense representations to jointly encode geometric structure and high-level semantics of dynamic environments.
Under review (2025)
Aligning Forest and Trees in Images and Long Captions for Cross-Domain Grounding
Byeongju Woo, Zilin Wang, Byeonghyun Pak, Sangwoo Mo, Stella X. Yu
We propose a hierarchical vision-language model that enables fine-grained multimodal understanding without extra annotations.
