About Me

I am an assistant professor in Department of Computer Science and Engineering at Ewha Womans University. I was a postdoctral research fellow for Cognitive Assistance Laboratory at Carnegie Mellon University, worked with Prof. Kris Kitani and Prof. Chieko Asakawa. Before then, I studied at University of Maryland, College Park as a member of Human Compter Interaction Lab, advised by Prof. Leah Findlater, where I received my PhD in Computer Science.


The goal of my research in Human Computer Interaction (HCI) is to enrich user experience with novel interaction technologies with minimum physical and cognitive loads. I am particulary interested in improving information access by redesigning state-of-art technologies (e.g., wearables, augmented reality) for individuals with various needs, especially for people with visual impairments.
