Seunghun Lee

I am an AI Engineer at Huawei Singapore. I received my Ph.D. and B.S. degrees from DGIST (Daegu Gyeongbuk Institute of Science and Technology), where I was advised by Prof. Sunghoon Im.

My research trajectory is built on a deep understanding of visual and multimodal systems. During the early stages of my doctoral studies, I focused on Domain Adaptation. I subsequently expanded my expertise into Video Perception, tackling tasks such as Video Instance Segmentation (VIS), Referring Video Object Segmentation (RVOS), and Moment Retrieval. Currently, my research interests are centered on Vision-Language-Action (VLA) modeling, exploring the intersection of multimodal reasoning and actionable intelligence.
