Hello! I am pursuing doctorate in KAIST under the supervision of Prof. Junehwa Song. Within the broad spectrum of mobile computing, my interests lie in mobile applications, systems, and human factors in mobile services. My researches have been published in top-tier conferences such as CHI, UbiComp, MobiSys, 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 with Inseok Hwang, Eric Rozner, Yu Gu, and Robert Dickerson.
