Hi! I am Yong-Han, a master's student in computer science at the 
University of Illinois Urbana-Champaign.
I design, research, and build software systems to improve user experiences and make interactions with digital information easier.
One product I built is NotiManager, a new notification interface and system that improves people's notification experience.
I also conducted a real-world evaluation of NotiManager, and the findings from this evaluation were published at ACM UbiComp 2024.
In the past, I was fortunate to work with and be advised by Dr. Yung-Ju Chang on my undergrad research in computer science and human-computer interaction at 
National Yang-Ming Chiao-Tung University (former: National Chiao-Tung University).
My research and industry experience includes being a research intern at the Human-Centered Design Lab at Polytechnique Montréal,
and a software engineer at Xaduro (a travel tech startup that was later acquired).
