Hello! I am an Assistant Professor in the Department of Computer Science and Engineering at Ulsan National Institute of Science and Technology (UNIST), where I lead the Ultimate Interface Lab. I am also an Affiliate Faculty in the School of GRIT Convergence Studies at UNIST and a Visiting Assistant Professor in the Department of Computer Science at the University of Virginia.

My research pursues the vision of the Ultimate Interface: an intelligent, physical, and adaptive user interface that takes the form and interaction mode best suited to the task, the user's situation, and their abilities. In my research group, we work toward this vision by designing new interaction paradigms, developing interaction technologies, and building interactive systems across diverse contexts. These efforts include both software and hardware systems and interfaces, with resulting work published in top HCI venues, including CHI, UIST, IMWUT, CSCW, and IJHCS, and receiving multiple Best Paper and Honorable Mention Paper Awards from CHI, MobileHCI, VRST, and ISS, as well as Best Poster Awards from UIST and IEEE VR. I am a recipient of a Meta Research Award and the Naver PhD Fellowship.

Before joining UNIST, I was the Alfred Weaver Career Enhancement Assistant Professor in Computer Science at the University of Virginia from 2019 to 2026, and a postdoctoral researcher in Computer Science at the University of Toronto working with Prof. Daniel Wigdor from 2017 to 2019. I received my doctoral degree in Computer Science from KAIST in 2017 under the guidance of Prof. Geehyuk Lee. During my studies, I had research internships at Autodesk Research, Microsoft Research, and Samsung Advanced Institute of Technology.

Outside research, I enjoy playing basketball and riding bikes of all kinds. I have joined school basketball competitions from high school through graduate school, and later faculty events at UVA; I never quite won one, though my team once made it to the final at a UVA ACM students-versus-professors game. I also used to do tricks on BMX and mountain bikes, and completed long-distance bike trips along the east coast of South Korea from Gangneung to Busan and the east coast of Australia from Brisbane to Sydney.
