Introduction    

Thomas Poell is Professor of Data, Culture & Institutions at the University of Amsterdam, program director MA Media Studies, and director of the Research Priority Area on Global Digital Cultures. His research is focused on the digitisation of cultural institutions in the light of the proliferation of data, the growing importance of AI, and the rise of major platform corporations. He explores how these developments lead to creative and economic upheaval in the media industries, as well as to a reorganization and rethinking of museums, libraries, and archives. Together with Olav Velthuis, he is currently leading an NWO-funded research project on The platformization of the global sex industry. And on 24 June 2022, he gave his inaugural lecture: Platforms, Power & Collectivity. 

Poell is co-author of Platforms and Cultural Production with David Nieborg and Brooke Erin Duffy (Polity, 2021) and The Platform Society with José van Dijck and Martijn de Waal (Oxford University Press, 2018). Furthermore, he co-edited The Sage Handbook of Social Media (Sage, 2018), Social Media Materialities and Protest (Routledge, 2018), and Global Cultures of Contestation (Palgrave/McMillan, 2017).

He has published 40+ articles in international peer-reviewed journals, including New Media & Society, Information, Communication & Society, Social Media + Society, Digital Journalism, Journalism Studies, Internet Policy Review, Chinese Journal of Communication, The Information Society, Social Movement Studies, Communication Theory, Big Data & Society, Television and New Media, and The International Journal of Communication. Finally, he is member of the editorial board of Social Media + Society, Digital Journalism, Journal of Digital Social Research, and Communication and the Public.
