I am an associate professor in the Department of Computer Science and Engineering of Seoul National University. I received my PhD from the computer science department of KAIST in 2013 and worked at Singapore Management University as an assistant professor until 2018. I am leading Human-Centered Computer Systems Lab. My group works at the intersection of mobile and pervasive computing, machine learning systems, and human-computer interaction. We are broadly interested in building experimental and innovative software systems, which involve multi-dimensional considerations across systems, applications, and users.
