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 and edge deep learning systems
    • Optimizations for resource-constrained devices
    • Power efficiency and concurrency support
  • Mixed Reality Systems 
    • MR interfaces and usability
    • Inference engines for mixed reality
    • Mixed reality simulation
    • 3D data processing and streaming
  • Human-Centered AI Applications
    • Interaction with ML models and systems
    • Healthcare, wellness, and accessibility applications
    • Generative AI for games
