Profile

The questions behind the work.

Christoph Trattner is Professor of Information Science at the University of Bergen and founder and director of SFI MediaFutures, the Research Centre for Responsible Media Technology & Innovation. His research focuses on responsible AI for media and health: how digital systems shape what people read, trust and choose.

He connects algorithm design with experiments on human behaviour. His media research spans responsible news recommendation, AI-supported journalism and content provenance. In health, he studies trustworthy information and AI-assisted decisions, with a longstanding focus on the healthiness and sustainability of online recipes and food recommendation. He is Principal Investigator of CuratedAI and VaccAI, and founder and leader of the DARS research group.

His work includes research in Nature Food, ACM RecSys and The Web Conference, alongside scholarly commentary in Science and Nature Sustainability. Through international academic and industry collaborations, he develops and evaluates systems designed to support informed choices and professional judgement.

Research & Practice Note accepted at ACM RecSys 2026

Our Research & Practice Note “Exploring Revealed Behavior and Stated Profiles in Longitudinal News Recommendation,” with Thomas Elmar Kolb and Alain Dominique Starke, reports a four-wave study with 262 participants. Preliminary results show that article-selection behavior shifts with feed composition while stated topic profiles remain comparatively stable—an important caution against treating short-term clicks or likes as stable preference change.

Full paper accepted at ACM RecSys 2026

Our paper “Reducing Perceived Polarization through Affect-Balanced News Reframing,” with Jia-Hua Jeng, Alain D. Starke, David Elsweiler and Christoph Trattner, has been accepted for the ACM Conference on Recommender Systems 2026.

Research

Three papers presented at ACM UMAP 2026 in Gothenburg

At ACM UMAP 2026 in Gothenburg, our team presented three papers spanning trustworthy news personalisation, selective news avoidance and AI-generated recipes. Tobias Wessel presented work on fact-checked LLMs for editor trust, Svenja Lys Forstner presented INRA work on explanations for low-interest news, and Yelyzaveta Lysova presented work on how users overlook nutritional flaws in LLM-generated recipes.

Research

CuratedAI and VaccAI awarded

Two Research Council of Norway mobility projects connected to SFI MediaFutures and UiB were awarded, strengthening work on AI transparency, media literacy, vaccine beliefs and trustworthy health communication.
