Volkmar Pipek

Volkmar Pipek, Prof. Dr., studied Computer Science and Economics at the University of Kaiserslautern, focussing on Database Systems and Artificial Intelligence. His research interest into interdisciplinary, more application-oriented computer science lead him to the Research Group on HCI and CSCW at the Institute for Computer Science III at the University of Bonn. He worked from July 1997 to December 1998 in the project POLITeam on “awareness” issues and organizational aspects of introduction and maintenance of groupware applications. 1999 he worked in several smaller projects on Knowledge Management and Distance Learning. From April 2000 to March 2003 he was coordinating the project OlViO, a project on the use of IT in Organisational Learning. From 2003-2005 he was a guest researcher with the Laboratory of HCI and Group Technology at the University of Oulu, Finland, where he received a PhD degree in Information Processing Science in early 2005. Currently he is an Assistant Professor with the Institute for Information Systems at the University of Siegen, Germany. He currently chairs to the board of trustees of the International Institute for Socio-Informatics (IISI).

Claudia Müller

Claudia Müller, Prof. Dr., assistant professor in Information Systems, in particular ‘IT for the Aging Society’ at the University of Siegen and professor at Kalaidos University of Applied Sciences, Switzerland, at the Careum Health Research Department, Zurich. Following her professional training as a registered nurse and professional practice in acute care and outpatient geriatric care and her master’s degree in cultural anthropology, history and theoretical medicine at the University of Bonn, her path led to applied computer science. Her interest in combining cultural anthropology and computer science was developed as a student assistant at the Fraunhofer Institute for Applied Information Technology (FIT) in St. Augustin in a project on software engineering for small and medium-sized enterprises. From 2006 she worked as a research assistant in Information Systems at the University of Siegen and received her doctorate there in 2013 on the topic of comparative design case studies in the field of participative IT design with vulnerable user groups. She is co-founder of the Siegen Praxlabs concept (

Markus Rohde

Markus Rohde, Dr., studied psychology and sociology at the University of Bonn and is one of the founders of the International Institute for Socio-Informatics (IISI) and co-editor of the International Report on Socio-Informatics. Since 2004 he is working as a research associate at the Institute for Information Systems and New Media at the University of Siegen, since 2008 as research manager for Community Informatics. Moreover he is editor of the political science journal “Forschungsjournal Neue Soziale Bewegungen” (New Social Movements). Since 1991 his research focuses on usability engineering of network systems, on virtual organizations, and on “organization and technology development”. From 1994 until 1997 he was working as a consultant for medium-sized enterprises and for nonprofit-organizations. From 1997 until 2001 he worked as CEO of AGENDA CONSULT GmbH. From 2002 until 2004 he was working as a project manager for IISI. In 2004 he was research associate for Fraunhofer Institute for Applied Information Technology (Fhg-FIT) in Sankt Augustin. In 2007 he awarded his Ph.D. degree in Information Systems at Roskilde University, Denmark. His main research interests are human-computer interaction, computer supported cooperative work (CSCW), expertise management and blended learning, virtual organizations, non-governmental organizations and (new) social movements.

Volker Wulf

Volker Wulf is a professor in Information Systems and the director of the Media Research Institute at theUniversity of Siegen. At Fraunhofer FIT, he heads the research group User-centred Software-Engineering (USE). He is also a founding member of the International Institute for Socio-Informatics (IISI), Bonn.

After studying computer science and business administration at the RWTH Aachen and the University of Paris VI., he got a Ph.D. at the University of Dortmund and a habilitation degree at the University of Hamburg, Germany. In 2001, he worked as a research fellow at the Massachusetts Institute of Technology (MIT), Cambridge, MA. Wulf spends right now a sabbatical as a Fulbright Scholar at the University of Michigan, Ann Arbor, and lateron at Stanford University, Palo Alto.

His research interests lie primarily in the area of Computer Supported Cooperative Work, Knowledge Management, Computer Supported Cooperative Learning, Entertainment Computing, Human Computer Interaction, Participatory Design, and Organizational Computing.

He published more than 170 papers. He edited 10 books among which „Expertise Sharing: Beyond Knowledge Management“ and „Social Capital and Information Technology“ both with MIT Press Cambridge MA and „End User Development“ with Springer Dordrecht are probably best known. As a conference co-chair he hosted the Seventh European Conference on Computer Supported Cooperative Work (ECSCW 2001) in Bonn and Communities & Technologies (C&T 2003) in Amsterdam.

Peter Mambrey

Prof. Dr. sc. pol., M.A. He directs the research group “Evaluation & Design” at the Fraunhofer Institut for Applied Information Technology FIT. His research interests are: technology assessment; participatived, socio-technical systemdesign and systemevaluation; methods about requirements engineering, communication plattforms for organisational lerning and virtuel organisations.

He teached as honorary professor at the University of Duisburg-Essen.

Since 1999 he is Chairman of the IFIP WG 9.1 „Computers and Work“.

Jens Rinne

studies till 09/2004 informatics at the university of bonn. He works between 03/2001 and 12/2003 as a student assistant at the Fraunhofer-FIT in Sankt Augustin. There he wrote his final thesis ‘Personal Hypertextpresentation to Improve Ranking and Query Expansion in a Collaborative Retrieval Environment’. The content of the thesis is the automative finding of relevant ‘WebSources’ associated to special interests of a human. This work lies in the field of Information Retrieval, Information Brokering and Software Robots. He developed the component ‘MyWebSource’ which is part of the knowledge tool ISKODOR, developed at the research group of information retrieval at the university of bonn.

Jens Rinne is one of the founders of the association ‘theGROUP e.V.’ which belongs the International Institute for Socio-Informatics (IISI). Actual he is one of two managing directors of the IISI.
