Norwegian Computational Behaviour & AI Lab
On a mission to improve our lives that transforms the way we consume food and media.
Research Focus
News, Polarization & Democracy
Selective exposure, emotional framing, editorial curation, and the role of generative AI in journalism and civic discourse.
Health, Food & Behaviour
Recipe recommenders, cross-country dietary patterns, and AI-based systems to assist healthier and sustainable food choices.
Networks & Digital Platforms
Human–AI interaction dynamics on platforms; predicting ties, participation, diffusion, and collective behaviour with agents in the mix.
Methods & Democratic AI
Large-scale experiments, causal analysis, and human-in-the-loop evaluation of AI-enabled systems anchored in democratic values.

Key Publications
