He is an Associated researcher at the Humboldt Institute for Internet and Society (HIIG), Berlin, that he helped to build up from 2011 onwards. Christian completed his PhD at Freie Universität Berlin with a dissertation thesis on “Governance, Technology and Communication” (2016, summa cum laude). The thesis was awarded the two-year dissertation prize of the German Communication Association (DGPuK) and the dissertation prize Media-Culture-Communication.

In research and teaching, Christian addresses the interrelationships of communication, technology and politics in the context of the digitalisation of society. Currently he focusses on the conceptual and empirical investigation of the regulation and governance of the internet and platforms, the role of data, algorithms and infrastructures for the (re-)organisation of societal communication, as well as discourses and regulation of “artificial intelligence”.

Christian leads large international third-party funded projects on these topics, funded by the DFG, the EU’s H2020 framework programme, the BMBF, the Volkswagen Foundation and the Federal Agency for Civic Education (BpB).
