Ryo Suzuki | University of Calgary Assistant Professor

Ryo Suzuki
University of Calgary, Assistant Professor in Computer Science

I am an Assistant Professor at the University of Calgary in the Department of Computer Science, starting in Winter 2021. I am part of HCI Group at UCalgary.

I am actively looking for PhDs, masters, postdocs, or interns, who are interested in joining or collaborating with us, across disciplines (e.g., Industrial Design, Mechanical Engineering, Material Science, Electrical Engineering, Architectural Design, and Computer Science). If you are interested, please feel free to send me an email. We could start from some possible collaborative projects. :)

My research interest lies on the intersection at Human-Computer Interaction (HCI) and Robotics. I direct Programmable Reality Lab at the University of Calgary, where we try to blend digital and physical worlds by exploring novel interactions for AR/VR, tangible, and shape-changing interfaces.

Previously, I was a PhD student at the University of Colorado Boulder, advised by Daniel Leithinger and Mark D. Gross in THING Lab and Human-Computer Interaction Group
