Martin Brynskov, PhD, is associate professor in interaction technologies at the Department of Aesthetics and Communication at Aarhus University in Denmark. He is also research fellow at Participatory IT Centre (PIT) and Center for Advanced Visualization and Interaction (CAVI), director of the Digital Design Lab, co--founder of Smart Aarhus, and former director of the Civic Communication group at the Center for Digital Urban Living. He is the general chair of the Media Architecture Biennale 2012 and 2014. Working closely together with municipalities, artists, journalists, media organizations, and industrial partners, he investigates the consequences of digitization and explores new forms of mediation within a variety of domains with special focus on the role of social interaction, materials and interfaces. The research is mostly carried out as interventions and experiments in the wild, deploying prototypes and semi--‐permanent interactive systems.
