Tanja studied German philology and political science in Trier. She has since worked as a researcher in various projects involving digitisation, virtual research environments, and scientific communication. She also has a background in public relations and a degree in Librarianship. At GESIS Tanja is primarily engaged in questions of data reference, data indexing, and data retrieval. In particular she is working on the establishment of a data reference system for the social sciences in the context of da|ra, the registration agency for social and economic data. Tanja's research interests include information behaviour studies and data indexing.


  • da|raSearchNet (Development of an integrated search network for social and economic data; project funded by DFG)
  • Management and translation of the German version of the European Language Social Science Thesaurus (ELSST)
  • Development of concept and guidelines for subject indexing of survey data


  • Information behaviour and information practices of secondary users of survey data
  • Subject indexing of survey data
