Hi! I am Yong-Han, a first-year master's student in Computer Science at the 
University of Illinois Urbana-Champaign.
Before starting my graduate studies, I worked on building research applications and studying people's experience with mobile media and notifications, aiming to help them spend their time on their phones more productively.
I am fortunate to be advised by Dr. Yung-Ju Chang.
As a student researcher and software engineer, I focus on projects related to advancing human-computer interaction and the use of machine learning models. I design, build, and study intelligent systems to empower users to consume and interact with digital information more effectively. In my recent work, I designed and built an intelligent notification system to facilitate users' workflows in reading and handling notifications. This was achieved through automated sorting and categorization, complemented by manual functions for users to adjust these automations. I also studied users' experiences with this system by using mixed-methods.
In the past, I did my undergrad in computer science at 
National Yang-Ming Chiao-Tung University (former: National Chiao-Tung University).
I also worked in the Human-Centered Design Lab at Polytechnique Montréal as a research intern,
and at Xaduro (a travel tech startup) as a software engineering intern.
