Hi! I'm a Postdoctoral Fellow at Carnegie Mellon University's Human-Computer Interaction Institute (HCII), working with Jeff Bigham.
I earned my Ph.D. from KAIST, advised by Juho Kim, with support from the NAVER PhD Fellowship and the Kwanjeong Scholarship. I've had the opportunity to intern at Adobe Research, Autodesk Research, and LG AI Research.
My research focuses on helping people learn new skills and perform complex tasks. I have developed AI-based systems that use instructional videos and AI agents to support users in completing procedural tasks. My current research focuses on building user-aware and collaborative AI agents that can adapt to individual users and work alongside them.
