I am a Senior Researcher at Samsung Research America (SRA), working on robotic manipulation, navigation, agentic memory, and multimodal intelligence for edge devices. Before joining SRA, I was a postdoctoral researcher at POSTECH, where I earned my Ph.D. in Computer Science and Engineering under Professor Minsu Cho. During my research journey, I collaborated with Google Research on multimodal video understanding with Cordelia Schmid, and with Microsoft Research Asia on bio-inspired machine vision with Chong Luo.
