About

Yusuke Koroyasu

I make things float with sound.

Using ultrasonic phased arrays, I levitate and manipulate objects in mid-air. My work — across both research and art — is driven by a single obsession: making invisible forces visible. Doctoral researcher at the Digital Nature Lab, University of Tsukuba. JSPS Research Fellow DC2. Alongside research, I create sound/visual performances and installations, exploring the boundary between sound and matter.
