Dr. Mikael Wiberg is an Assistant Professor at the Department of Informatics at Umee University in Sweden. He is currently director for graduate studies and chair for the advisors group at the department. He received his Ph.D. in Informatics at Umee University in 2001. The topic for the thesis was design of mobile CSCW (Computer Supported Cooperative Work) systems with a special focus on design for informal communication and ongoing interaction. In his current research he is focused on the emerging Interaction Society with related issues including e.g. mobile CSCW, mobile meetings, knowledge management in mobile settings, proximity based interaction, mobile pervasive and ubiquitous computing, and session management for sustained and dynamic interaction across physical and virtual arenas. In 2000 he founded the Mobile business research group and currently Mikael Wiberg is leader for the ITL Interaction Theory Lab that he founded in 2002. The research at ITL typically includes empirical user studies (e.g. ethnographic studies and naturalistic studies), theoretical work, and design and evaluations of prototype systems. He is also project manager for a EU-funded research project called Meetings where he is doing research on design of novel IT-support for co-located social interaction. Mikael Wiberg has published several articles and presented several papers about design of mobile, pervasive and ubiquitous IT-use.
