Social Media · Information Integrity · Human–AI Interaction
Mohsen Mosleh
I am Associate Professor at the University of Oxford, Governing Body Fellow at Wolfson College, Research Affiliate at MIT, and Member of the World Economic Forum Council on Information Integrity. I am Associate Editor of EPJ Social Data Science and Member of the Editorial Board of Advances in Psychology.
My research combines computational social science, large-scale social media analysis, online field experiments, and AI/LLM evaluation. I study misleading narratives, cross-platform information diffusion, trust and safety, human–AI interaction, and interventions to improve the quality of online discourse. My work has been published in Nature, PNAS, Nature Communications, and Psychological Science, and supported by the British Academy, Meta, Google, and the UK Department of Science, Innovation & Technology.
I occasionally advise organisations and start-ups on AI, information integrity, online interventions & experiments, and social media intelligence analysis — helping teams with evaluation frameworks, research strategy, and product validation.
