As a computer scientist, UX researcher, and front-end developer, my interest is at the intersection of Human and Arti cial Intelligence. I develop interactive systems for collecting high-quality data for machine learning, visualizing complex models for ordinary people, and coupling human and AI to solve challenging problems. I received PhD of Computer Science at University of Maryland, MSc. Design for Interaction at Delft University of Technology, the Netherlands. I also have BSc. Industrial Design and BSc. Computer Science (minor) from KAIST. During my graduate studies, I was fortunate to intern at Microsoft, IBM Research Center, and Adobe Research.
