Seongkook Heo

I am a Postdoctoral Research Fellow in the DGP lab at the University of Toronto, where I work with Prof. Daniel Wigdor. I received my PhD in Computer Science at the KAIST in 2017, advised by Prof. Geehyuk Lee.

I design, build, and study new user interfaces and interaction techniques to make the interaction between humans and computers rich and nuanced like we do in the real world.
