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.

Aligning Forest and Trees in Images and Long Captions for Visually Grounded Understanding
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.
