Christopher Salter studied economics and philosophy and received his PhD in theatre and computer generated sound at Stanford University. His theoretical interests and artistic practise investigates the role of real time digital sound, image and technologies of interaction within the context of sensor-based environments and live performance. He has collaborated with, among others, Peter Sellars, and William Forsythe and the Ballet Frankfurt. He co-founded the art and research organisation Sponge, whose works have stretched between artistic production and scientific research. Salter is researcher in interactive performance/sound in the Hexagram Institute for Research/Creation in Media Arts and Sciences and author of the forthcoming book Entangled: Technology and the Transformation of Performance from MIT Press.
