I research things.

I'm a PhD student in the Waterloo HCI Lab, supervised by Daniel Vogel. My research focuses on making VR more accessible. This includes working with accessibility-oriented communities, developing assistive technologies and interaction techniques for VR, and working with developers to implement these techniques.
