was born in Vienna and lives and works in Berlin and Vienna. While studying art and philosophy he began exploring the potentials of a dynamisation of the relationship of artwork and viewer. He developed the ”solo action”, a format between exhibition and performance, in which the spectator perspective as being opposite is dissolved into a point of view that is itself part of the artwork. With reference to ancient beginnings of the viewing dispositive of European art and theatre and a related partitioning of space that is still effective today, he pursues his research on sight and space with various means, from installation to sculpture, over performance and dance to photography and video. Together with Sandra Man he is working on an artistic practice that is based on the conception of space as happening, and which incorporates the bodies and senses of the audience: space choreography.
