Hiroaki MASAKI

I'm Hiroaki Masaki(正木 博明). My research interest lies in Human-Computer Interaction(HCI). More specifically, my research focuses on "nudge", well studied in behavioral economics, and mobile health. In my spare time, I like listening to radio and manzai, watching baseball, participating to marathon, and eating curry.
