I am a Ph.D. student in the Robotics Program at the Korea Advanced Institute of Science and Technology (KAIST), advised by Kuk-Jin Yoon in the Visual Intelligence Lab.
My research focuses on building robust and data-efficient omni-modal models with minimal human supervision.

I am open to research collaborations, coffee chats, and internship or full-time opportunities. Please feel free to contact me 🤗.

• My research aims to build reliable and data-efficient multimodal intelligence under practical constraints on data, compute, supervision, and sensing. I first encountered these challenges while developing real-time perception systems for autonomous driving under adverse weather using visual, LiDAR, and fused sensor inputs [J1, C1, C2, C5]. This work showed that reliable deployment requires models to generalize beyond controlled training conditions while satisfying strict requirements on latency, safety, and computational efficiency.

• I subsequently investigated model reliability more directly by developing transferable adversarial methods that expose vulnerabilities in black-box systems across different architectures [W2→C3, C4, W3→C6]. These studies showed that reliability depends not only on the robustness of individual encoders, but also on whether their learned representations preserve meaningful structure when models, inputs, or environments change. This perspective led me to vision-language learning, where the central bottleneck is often not model scale alone, but the cost, noise, and limited correspondence of multimodal supervision. My current work therefore develops data-efficient and geometry-aware methods for identifying and preserving useful cross-modal correspondence under limited and imperfect image-text supervision [C7, C8].

• Building on this foundation, my future research comprises three connected directions: data-efficient multimodal learning, robust cross-modal alignment, and Physical AI Alignment. I aim to develop compact and transferable supervision for training and adapting multimodal models across architectures, modalities, and downstream tasks. I then seek to align independently pretrained modality experts so that they can reinforce one another without retraining from scratch, while remaining reliable under distribution shifts, corrupted or missing modalities, and adversarial perturbations. In the future, I plan to connect multimodal representations with perception, prediction, memory, and action, enabling embodied systems and world models to learn efficiently from heterogeneous real-world experience. My long-term goal is to establish general principles and open evaluation frameworks for omnimodal models that are efficient, robust, and deployable beyond controlled benchmarks.
