About
I am an Assistant Professor in the Department of Computer Science and Engineering at Sungkyunkwan University (SKKU), where I lead the Future Computing Lab (FCLab). My research lies at the intersection of AI Agents, Frontier Interfaces, and human-computer interaction.
I am interested in computer-use agents that can understand and operate software interfaces, and in AI-native interfaces that move beyond today's app-centric interaction models. More broadly, I explore how intelligent systems can reshape the relationship between people, software, and the devices around them.
Ultimately, I design a new computing paradigm in which AI is not merely added to existing software, but becomes a natural and trustworthy part of how computing systems are designed and experienced.
