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 mobile and pervasive computing, applied machine learning, 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:
- Edge AI Systems
- On-device and edge deep learning systems
- Optimizations for resource-constrained devices
- Power efficiency and concurrency support
- Privacy-preserving deep learning
- Human-Centered Sensing
- Behavior sensing and analytics
- Emotion and health sensing
- Healthcare, wellness, and accessibility applications
- Social science computing
- Mixed Reality Systems
- Augmented and virtual reality systems
- Multi-modal interactions
- Mixed reality applications and usability
- 3D media streaming
