At Neubility, I lead 3D/4D scene perception for autonomous urban delivery robots. I developed VPE-Neubie, a multi-camera pipeline that unifies detection, depth estimation, open-vocabulary recognition, and segmentation, running at 25FPS on a Jetson Orin.
I also proposed GAPT, a post-training quantization framework that protects grounding-critical pathways in vision–language models, and developed SAD-LoRA for distillation-based compression. I prototyped long-horizon vision–language–action policies and validated them in NVIDIA Isaac Sim and CARLA.
At KAIST, I proposed domain-invariant inertial localization architectures and developed privacy-preserving federated learning systems. My work spans embodied AI, efficient multimodal models, robotics, and edge deployment.
