Prof. Dr. Judith Möller

Scientific Director

Judith Möller has taken up the professorship “Empirical Communication Research, especially Media Use and Social Media Effects” at Universität Hamburg in cooperation with the Leibniz Institute for Media Research | Hans-Bredow-Institut (HBI) on 1 February 2023. This is a joint appointment, which combines teaching at the University’s Institute of Journalism and Communication Studies with extensive research activities at the HBI.

Her research focuses on the effects of political communication, especially in social media. The focus is on two questions: (1) the impact of personalised political communication on individuals and society as a whole, and (2) the role of (new) media in the process of opinion formation, especially as part of political socialisation processes.

Judith Möller war Associate Professor of Political Communication at the Department of Communication Studies, University of Amsterdam (UvA) and Associate Professor at the Department of Sociology and Political Science, University of Trondheim before. She is an associate member of the Amsterdam School of Communication Research (ASCoR), the Center for Politics and Communication (CPC) and the Information, Communication, & the Data Society Initiative (ICDS).

In 2019, Judith Möller received a VENI Talent Track grant from the Netherlands Science Foundation (NWO). The project is entitled “Vocal, Visible and Vaulting? (Dis)connected Niche Audiences in the Age of Artificial Intelligence” and investigates the impact of algorithmic filtering systems and artificial intelligence on specific populations and niche audiences. Her work has been published in numerous international journals. She is a member of the editorial board of the Journal of Communication and Political Communication and an ad hoc reviewer for leading journals in the field.

Transfer

The transfer of her research and collaboration with practitioners is of great importance to Judith Möller. She regularly participates in public debates or science festivals and is in constant dialogue with newspaper publishers, public broadcasters and media regulators. For the German media authority Medienanstalten, she contributed to an expert opinion on types of disinformation and misinformation, which looked at different forms of disinformation and their dissemination from a communication science and legal perspective. She is also regularly invited as an expert to meetings of media regulators and consumer and market authorities, such as the European Regulators Group for Audiovisual Media Services (ERGA), the European Platform of Regulatory Authorities (EPRA), Medienanstalt Berlin-Brandenburg (mabb), Landesanstalt für Medien NRW, the Swiss Federal Media Commission (EMEK) or Election Observation and Democracy Support (EODS).

The Digital Services Act (DSA) is supposed to provide a remedy against election manipulation. In a blog post on the Verfassungsblog, Jan-Ole Harfst explains why Art. 34-35 of the DSA could hardly remedy the systemic risks of this federal election campaign.
