The “Socio-Informatics Symposium 2025” on Friday, April 4, is a special one as it will be held in memorial of Prof. Dr. Volkmar Pipek, particularly of his achievements and lifelong research work in the field of Computer-Supported Cooperative Work and Social Media.

Prof. Dr. Volkmar Pipek was a pioneer in Socio-Informatics. Like hardly anyone else, he succeeded in bringing together technological innovation and societal demands. In his work, he had a great capability in aligning academic theory building with societally relevant practices. In his theoretical contributions he lined out the concepts of appropriation, appropriation support, and infrastructuring. He also founded the FabLab in Siegen, a design-oriented space for exploration at the intersection of university, industry, and civil society.

We also honour Prof Dr. Peter Brödner, a pioneer of the German socio-technical design discourse. In overcoming tayloristic principles of organization and strenthening the importance of qualified and semi-autonomous labour, his work made him a visonary of the Siegen School. Peter taught more than 20 years in a charimatic manner to the great excitement of our students.

All sessions of the conference will take place at the University of Siegen, Campus Unteres Schloss (US-C), Unteres Schloss 3, 57072 Siegen (Maps).
