I am a daydreamer, engineer, and designer who dreams of the unreal and struggles to make it real a bit at a time, driven by novel mobile, intelligent, and interactive technologies embodied in the physical world.

The key driving forces of my research are next-generation intelligent mobile computing systems, novel socio-physical interaction, and multi-domain integration towards ubiquitously available services in the real world. In particular, a major theme throughout my research is to define and premiere innovative software systems that empower our everyday life with new socio-cognitive abilities beyond our natural-born limits. In pursuit of such a vision, my research deeply concerns the technical problems and design issues in dealing with resource-constrained computing platforms, optimizing the sensory and AI subsystems, and orchestrating computational elements and human factors to build an end-to-end system. My research has generated a number of experimental systems built with mobile, IoT, cloud, robotics platforms, as well as inspirations from unprecedented real-life applications in various domains, including health and well-being, family support, childcare, social activism and media, cyber-physical instrumentation, and so on.

To date, I have been serving on the program committees and/or editorial board of a number of premier academic venues leading my areas of research, including ACM MobiSysACM UbiComp/IMWUTACM CHIIEEE INFOCOM, and so on. I served on the NSF panel as a panelist to review grant proposals. I am a recipient of the Best Paper Awards in ACM CSCW 2014. My research has generated 30+ papers at premier venues and 40+ issued U.S. patents so far.

I joined IBM Research in 2014 as a Research Staff Member (full-time). Before joining IBM, I was a Research Assistant Professor at Center for Mobile Software Platform in KAIST, Korea. I received my Ph.D. in Computer Science from KAIST in 2013 under the advisement of Dr. Junehwa Song, and B.S. / M.S. in Electrical Engineering from KAIST.

Just a prosperous day at work :-)
