I am currently a first-year Ph.D. student at the Human-Computer Interaction Institute at Carnegie Mellon University, working with Dr. Jeff Bigham and Dr. Amy Pavel. I am also an Adobe Research Ph.D. Fellow. Previously, I completed my B.S. in Computer Science at National Taiwan University, where I worked with Dr. Mike Chen and Dr. Lung-Pan Cheng.

My research lies at the intersection of inclusive and immersive experiences, with a recent focus on building systems to facilitate accessible content consumption and creation. I also did work in the fields of computational interaction, virtual and augmented reality, haptics and perception.

Selected Research
A presenter view of a slide from a lecture where most text is in black but some of the text has been colored green to represent that it has been spoken by the presenter (as the speaker said 'activity: create a colorful circle brush'). There is an image with a squiggly circle brush on the slide highligted with green border to indicate that the image has also been mentioned.
Say it all: Feedback for Improving Non-Visual Presentation Accessibility


An authoring system that visualize real-time and post-hoc accessibility feedback for speakers to deliver more accessible presentations.
