Research Interests

I am an assistant 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 since then as an assistant professor before I joined Seoul National University in 2018. I have broad research interests in building experimental and innovative software systems, which involve multi-dimensional considerations across operating systems, applications, and users. More specifically, my research interest lies in building mobile, IoT, AI systems to enable always-available and highly-enriched awareness on human behavior, emotion, and surrounding contexts. Furthermore, I have built and deployed ML/DL-enabled life-immersive sensing applications in various application domains such as daily healthcare, childcare, education, and retails in collaboration with domain experts. I summarized my research interests as below. 
  • Human Behavior and Context Sensing
    • Behavior sensing and analytics (activity, group, conversation, etc.)
    • Emotion and health sensing (stress, depression, engagement, etc.)
    • Localization and location analytics
    • Healthcare, wellness, and accessibility applications
  • Mobile and Embedded Machine Learning
    • Mobile deep learning systems
    • Model optimization for resource-constrained devices
    • Power efficiency and concurrency support
    • Privacy-preserving deep learning  
  • Systems and Tools for Emerging Devices 
    • VR-enabled data generation tool for ML/DL model training
    • VR-enabled app design tool for accessibility 
    • Debugging and testing tools for IoT and sensor devices
    • Innovative user interaction techniques
  • Large-Scale Data Analytics Platform
    • Large-scale mobile testbed (smart campus and smart city) 
    • Urban data analytics (traffic, groups, crowds, etc.)
    • Computational social science
