Georg Essl is a Senior Research Scientist at the Deutsche Telekom Laboratories at the Technical University of Berlin in Germany and founding member of the Mobile and Physical Interactions group at the chair for Quality and Usability. He works in two main areas: human computer interaction and interface emphasising sensory modalities and interfaces and physically based rendering of natural (and not so natural) sounds. In recent years he has been emphasizing interactions with mobile technologies, mostly to make them richer and more expressive, so that they can be used more performatively (think making music or just noise with them, or to prefigure uses in other forms of entertainment (uh-oh mobile games). He is also working on sound synthesis, with the basis of trying to understand the basic structures of the problem. Most of his recent work has been on wave propagation in the plane but also on non-physical methods like circle maps as the simplest chaotic but stable perturbations of a linear discrete oscillator.
Before coming to Berlin, he worked as a post-doctoral researcher at MIT's MediaLab Europe with Sile O'Modhrain on tangible interactions. PebbleBox, a tactile interface for sonic performance which he built with Sile O'Modhrain and Andy Brady, was invited to the Touch Me exhibition at Victoria and Albert Museum, London in 2005. While at Media Lab Europe, he participated in the Enactive European Network of Excellence, which studies the role of action in interaction design. Between 2002-2003 he was Assistant Professor in Computer and Information Science and Engineering at the University of Florida, where he taught signal processing and synthesis of sound and digital production. He got my Ph.D. in Computer Science from Princeton University in 2002 working with Perry Cook on physical simulation of musical instruments. He also worked some on spatial audio technologies and beat perception. He received a Diploma Engineer's degree from Graz University of Technology, Austria. Additionally he has worked at AT&T Research Labs on perceptual spatial audio and at HyperWave R&D on a commercial database integrated web server technology. A web management technology he co-developed at HyperWave won the European IT Grand Prize and two BYTE's Best of CeBit awards in 1997.
He is a member of the IEEE, the Acoustical Society of America (ASA), the International Computer Music Association (ICMA), and the American Mathematical Society (AMS). He serves as technical chair for the International Computer Music Conference in 2004 and 2006. Currently he serve as Research Coordinator of the ICMA.
