Research Interests


I am an associate professor in the Department of Computer Science and Engineering of Seoul National University. I received my PhD from the computer science department of KAIST in 2013 and worked at Singapore Management University as an assistant professor until 2018. I am leading Human-Centered Computer Systems Lab. My group works at the intersection of machine learning systems, pervasive computing, and human-computer interaction. We are broadly interested in building experimental and innovative software systems, which involve multi-dimensional considerations across systems, applications, and users. Our current research interests are summarized below: 
  •   Machine Learning Systems
    • On-device deep learning systems
    • Lightweight AI models
    • Continuous perception and reasoning
  • Mixed Reality Systems 
    • Multi-modal sensing and perception
    • Spatial understanding and reasoning
    • Interfaces for mixed reality
  • Interactive AI Agents
    • AI agents for games, education, and healthcare
    • Handling uncertainty of AI algorithm and real-world contexts 
    • Privacy-aware interaction
