Hi! I'm a 4th-year Ph.D. student in the School of Computing at KAIST. I am working with Juho Kim as part of KIXLAB.
My research interests in Human-Computer Interaction lie in video understanding and interaction. I leverage HCI and AI techniques to comprehend video content and build interactive technologies that empower users to create and consume video content more effectively. In particular, I aim to improve how people learn procedural tasks through instructional/how-to videos to achieve everyday tasks.

Keywords: Human-Computer Interaction; Computer Vision; Video Interaction; Multimodal Understanding; Procedural Task;
