I am researching HCI / XR technology.  My research vision is to connect communication and education with advanced technologies like HCI / XR / machine learning.  I want to enhance communication UX using online spaces or virtual spaces.

Research Interests

As technology side, I'm interested in XR tech, machine learning and IoT.  I'm widely curious about technologies and not sticking to one category.

I welcome any collaboration with researchers and partners who have the same passion. Feel free to contact me.
