I am an assistant professor at Penn State's College of Information Sciences and Technology (IST). I run Design Square, a group of researchers and students at Penn State's IST studying Human Computer Interaction (HCI) and Health Informatics. With a background in HCI, Health Informatics, and Industrial Design, I study how we can design technology to promote healthy behaviors. In particular, I explore ways to support self-monitoring practices such that people can collect personal data easily, learn their behavioral patterns, and develop positive changes for health. My dissertation is titled, "Designing Self-Monitoring Technology to Promote Data Capture and Reflection." During my graduate studies I was fortunate to intern at a number of great research labs including Microsoft Research in Redmond and Intel Labs in Seattle. My enthusiasm for design led me to work at Google as a user experience design intern, and my internship project—designing the entire user interfaces of Google Video Chat—was successfully launched in 2008 and had been used by millions of people. In 2013, I was honored as a Google Anita Borg Scholar. I received my Ph.D. degree in Information Science from University of Washington, MS degree in Information Management and Systems from University of California, Berkeley and BS degree in Industrial Design from KAIST. You can see my CV. I am currently working on the following research topics:
