Golan Levin is an artist/engineer interested in the exploration of new modes of reactive expression. His work focuses on the design of systems for the creation, manipulation and performance of simultaneous image and sound, as part of a more general inquiry into formal languages of interactivity, and of communications protocols in cybernetic systems. Through performances, digital artifacts, and virtual environments, often created with a variety of collaborators, Levin applies creative twists to digital technologies that highlight our relationship with machines, make visible our ways of interacting with each other, and explore the intersection of abstract communication and interactivity. He writes: "I am interested in the medium of response, and in the conditions that enable people to experience creative feedback with reactive systems. I am drawn to the revelatory potential of information visualization - whether brought to bear on a single participant, the world of data we inhabit, or the formal aspects of mediated communication itself. And I am fascinated by how abstraction can connect us to a reality beyond language, and the ways in which our gestures and traces, thus abstracted, can reveal the unique signatures of our spirits." Levin is Associate Professor of Electronic Art at Carnegie Mellon University, Pittsburgh.
