About

I am Assistant Professor at the Department of Communication Science of the Vrije Universiteit Amsterdam and Research Associate at the Reuters Institute for the Study of Journalism, University of Oxford, where I was formerly a Postdoctoral Research Fellow from 2017 to 2023.

I study how people navigate news and political information online and its effects on democracy. My research agenda focus on how digital technologies are reconfiguring the news media ecology, borrowing tools from network science, and leveraging digital trace data.

Central to my studies is the role of technological platforms including social media, messaging apps and AI chatbots in mediating news consumption and shaping people’s attitudes towards media, politics and democracy.

I have conducted extensive research on the diversity of news media diets across platforms and countries and the specific effects of social media platforms on the ideological and substantive diversity of news consumption (i.e., echo-chambers). 

More recently, I am leading now a research project on the effects of socially interactive AI agents –like chatbots, smart speakers and robots– on attitudes towards news and openness to opposing views.

I have also been granted and XS NWO Research Grant by the Dutch Government to study the prevalence of echo-chambers in the offline media domain (i.e., television) leveraging multimodal large language models. As part of the European Consortium What-if, I am studying the effects of quality news diets and media literacy training on combating fake news on Spain, the Netherlands and Romania. 

I have extensively worked on advancing the news audience research field by proposing new methodological approaches to the study of news audience navigation patterns based on developments from network science. My work has been published in the Proceeding of the National Academy of Science, Political Communication, Journal of Computer Mediated Communication and Journal of Communication among others. It has received the economic support of the University of Oxford, the Dutch Government, the Royal Academy of Science in the Netherlands (KNAW) and the European Union. 

Moreover, my research has been tailored as reports, factsheets, interviews, media documentaries, or policy briefings to help the media industry and journalists in their decision-making processes.
