On 11 September 2026, my doctoral student Johanna Muhrbeck successfully defended her thesis, Beyond Orchestration: A Practice-Based Study of State-Linked Disinformation on Social Media, at the Department of War Studies, Swedish Defence University. Congratulations, Johanna, on this achievement!

Her research shows that state-linked disinformation spreads through more than coordinated campaigns. Once misleading content enters social media, users with no connection to the original actor can also contribute to its circulation. The thesis offers valuable insights for researchers and practitioners working to understand disinformation and strengthen societal resilience.
