I am a Postdoctoral Associate in Information Studies at the University of Maryland, College Park, working with Eun Kyoung Choe (2019-present).
In December 2021, I will join as a research scientist. At NAVER, I will collaborate with my colleagues to build up the HCI research threads.
As a Human-Computer Interaction researcher, I do research at the intersection of Ubiquitous Computing, Personal Health Informatics, and Personal Data Visualization. Combining my multidisciplinary knowledge in Computer Science and Visual Communication Design, I design and develop computing systems for self-tracking that empower people in the loop of human-data interaction in self-tracking.
I received a Ph.D. degree in Computer Science and Engineering (2012-2019, advised by Jinwook Seo), and a Bachelor of Fine Arts degree in Visual Communication Design (2007-2011) from Seoul National University.
I am a recipient of Korea International Postdoc Fellowship supported by National Research Foundation of Korea in 2019. I received a Best of CHI Honorable Mention award at ACM CHI 2021.
Data@Hand: Multimodal Data Exploration of Personal Data
It is tedious to explore personal data on a smartphone. We designed and developed Data@Hand, a mobile data exploration app that allows people to combine speech with touch interaction for fast and intuitive data exploration.

OmniTrack for Research: a Flexible Mobile In-situ Data Collection Platform
Study instrumentation of in-situ data collection on mobile devices consumes time and resources. We built an open source research platform with which researchers can device data collection studies and deploy self-trackers to their participants' smartphones. We used the tool to conduct many research studies.
