AI Research Engineer, NAVER Cloud (Image Vision)
I'm an AI Research Engineer at NAVER on a mission to build AI that truly understands the visual world. My journey began in core visual recognition — segmentation, detection, and matting — with 13+ papers at CVPR, ICCV, NeurIPS, ICLR and AAAI (570 citations, h-index 9). I'm now extending that perception expertise into multimodal & vision-language models — perception-grounded VLMs and visual reasoning agents that don't just see, but reason and act. My north star: research that ships — turning frontier ideas into products used by millions. I'm also pursuing my Ph.D. at KAIST alongside full-time research at NAVER.
Extending my visual-recognition expertise to vision-language models — multimodal LLMs/VLMs with fine-grained visual perception and grounding, and visual reasoning agents that perceive, localize, and reason over images.
Promptable, zero-shot segmentation & matting for anything; label-efficient human matting.
ZIM (ICCV'25 Highlight) · WSSHM
Weakly- and semi-supervised semantic & instance segmentation from cheap supervision.
PointWSSIS · BESTIE · DRS · WSSS-BED
Class-incremental and panoptic continual segmentation; lightweight, efficient models.
ECLIPSE · SSUL · EResFD · PfLayer
A diagnostic framework for 3D spatial reasoning that turns silent perception failures in visual program synthesis into typed diagnoses, driving targeted program repair to rival frontier VLMs without task-specific training.
A segmentation mask-refinement framework that synthesizes realistic, semantic-aware errors via adversarial perturbation and corrects them with contrastive learning, consistently improving state-of-the-art segmentation models.
