Building responsible AI that people can understand, question and trust.

Christoph Trattner is one of Europe’s leading experts and a research and innovation leader in responsible recommender systems, computational user behaviour, and trustworthy AI. With more than 20 years of experience at the intersection of academia, industry, and applied AI innovation, he helps organisations design, evaluate, and govern AI systems that influence human decision-making in high-impact domains such as media, health, food, and consumer behaviour.

He is a Full Professor at the University of Bergen, Director of the Research Centre for Responsible Media Technology & Innovation (SFI MediaFutures), and founder and leader of the DARS research group, Norway’s largest research group on recommender systems. He also leads the Norwegian Computational Behaviour & AI Lab, where interdisciplinary teams develop responsible AI solutions for real-world societal and business challenges. In addition, he is a founding member and board member of NoSoCSS, an interdisciplinary initiative advancing computational social science in Norway and beyond.

Trattner has initiated and led large-scale research and innovation collaborations involving startups, public-sector organisations, multinational companies, and policy stakeholders across Europe and the United States. He has also been invited by governments and public authorities to provide policy input, including by the Norwegian government to discuss research–industry collaboration. As founder and director of SFI MediaFutures, he conceived and built a national research–industry ecosystem that translates responsible AI research into practical technologies for journalism, media production, recommendation, fact-checking, accessibility, and democratic resilience.
