About
I am an Assistant Professor in the Department of Computer Science and Engineering at Sungkyunkwan University (SKKU). I design and build next-generation computing systems that seamlessly integrate AI with human workflows and everyday interfaces.
My recent work spans: GUI & Computer Use Agents that enable AI to autonomously navigate and interact with any software interface; Distributable User Interface systems for ubiquitous and context-aware mobile computing; and Human-AI-Computer Interaction (HACI) systems that redefine how humans and AI collaborate.
Currently, my team is synthesizing these directions to pioneer the foundation of a next-generation operating system—one where intelligent systems understand user intent, adapt interfaces across devices and contexts, and work in harmony with people in their everyday digital environments.
If you're interested in learning more about my works or exploring potential collaborations, feel free to reach out at sunjae.lee@skku.edu.
