I am a professor at the University of Stuttgart. My central research interests are novel user interfaces and innovative applications enabled by ubiquitous computing. Before moving to Stuttgart I was a professor at the Univeristy of Duisburg-Essen, had a joined position between the Fraunhofer Institute for Intelligent Analysis and Information Systems (IAIS) and the University of Bonn. I studied computer science in Ulm and Manchester and afterwards worked as a researcher at the University of Karlsruhe and at Lancaster University. There I completed in 2003 my PhD thesis on the topic of "Ubiquitous Computing - Computing in Context". Before I became professor at the B-IT-Center I headed the DFG-funded "Embedded Interaction Research Group" at the Ludwig-Maximilians University in Munich. My teaching and research interests are in media informatics and in particular in the areas of user interface engineering, pervasive computing and mobile interactive systems.
