I am a Ph.D. student at Human-Computer Interaction Institute (HCII) at Carnegie Mellon University (CMU), advised by Dr. Jeffrey Bigham and Dr. Amy Pavel. My current research focuses on designing and building interactive tools to support accessible media consumption and content production.

Before joining CMU, I was a member of HCI Lab at National Taiwan University (NTU), advised by Dr. Mike Y. Chen and Dr. Lung-Pan Cheng. As an undergraduate research assistant, I explored and developed several different enabling and inclusive systems across mixed-reality, mobile and wearable interfaces (see publication page for details).
