Dr Ioannis Michaloudis has experimented with NASA's nanomaterial silica aerogel as a sculptural medium, and is the first visual artist worldwide using this ethereal material in art. Although originally designed as a space technology material to capture stardust and act as a spacecraft insulator, he has resituated this material into a practice which is allegorical of the creation of sky, clouds and the ether.Yuri Tanaka is currently a Postdoctoral Researcher at Tokyo University of the Arts, where she received her PhD.
