Primary fields of research

My research is placed at the intersection between infrastructure studies, political economy of communication, and critical data studies. My focus is evenly on the role of the internet in everyday life as well as the societal implications of big data, digital infrastructures, and emergent business models, and counts the following topics:

• Datafication and online tracking with a specific focus on digital infrastructures, visibility, and political economies
• Methodological development and digital methods in digital media and communication research
• Sociological media and communication theory

Current research

I currently work on four interraleted research projects:

Mobile Surveillance Infrastructures explores mobile datafication and monetisation from the perspective of apps and other infrastructures directly related to mobile communication and mobile data flows, including app stores, operating systems, and third-party services.

Infrastructures of tracking investigates cookie-based tracking of users across websites and maps data flows and ownership structures as they relate to sites and trackers in Denmark and the rest of the EU.

Capabilities at the intersection between digital communication discusses and develops the Capability Approach within the field of media and communications in order to operationalise the approach and apply it to studies of communication, wellbeing, and justice, also within the realm of feminist media studies.

The Peoples' Internet (PIN) is an international project led by Professor Klaus Bruhn Jensen and funded by the Carlsberg Foundation. I did my PhD fellowship within this project, which charts the current and future state of the internet in three central regions - China, the US, and Europe.

Teaching
