Prof. Dr. Michael Rohs

Since July 2012, I am a Professor of Human-Computer Interaction in the Faculty of Electrical Engineering and Computer Science at the Leibniz Universität Hannover, Germany.

My primary research interests are in mobile human-computer interaction, mobile interactive media, and pervasive computing. My work focuses on novel interaction techniques for mobile devices, applications of computer vision techniques in mobile HCI, the usage of sensors for mobile interactions, and the integration of physical and virtual resources in the user's environment.

I received a Diplom in Computer Science from the Technische Universität Darmstadt, Germany, a Master's degree in Computer Science from the University of Colorado at Boulder, USA, and a Ph.D. in Computer Science from ETH Zurich, Switzerland. In the past, I worked as a research assistant in the Distributed Systems Group at ETH Zurich and as a senior research scientist at Deutsche Telekom Laboratories, Technischen Universität Berlin, Germany.
