About
Hello! I’m Junyoung Sung. I am currently working as an undergraduate researcher at ALIN Lab, KAIST, advised by Prof. Jinwoo Shin. Previously, I have done my research internship at MIIL, Korea University, advised by Prof. Paul Hongsuck Seo. My research focuses on robotic foundation models that can generalize effectively to diverse and dynamic real-world situations. Recently, I have been particularly interested in data-centric approaches to robot learning, including synthetic data generation and leveraging large-scale human video data to address the scarcity of robot interaction data.
