Hello! I received Ph.D. in Computer Science at KAIST in 2018. Within the broad spectrum of mobile computing, my interests lie in mobile systems and applications for in-situ social interaction in real world. Recently, I am interested in mobile systems for visual sensing and recognition. My researches have been published in top-tier conferences such as MobiSys, CHI, UbiComp, SenSys, and CSCW. In particular, I enjoy practical researches and implementation of working prototypes for real deployment. I worked at IBM Research Austin as a research intern, 2015 and 2017. In 2016, I received Google PhD Fellowship. [my CV]
