You have arrived at Sune Lehmann's site. I (Sune) am a Professor of Networks and Complexity Science at the Technical University of Denmark (DTU), and also a Professor of Social Data Science at the University of Copenhagen. A physicist by training, my research uses massive datasets and methods from complex systems, machine learning, and network science to understand human behavior — from how we move through cities to how information spreads online. I'm a member of the Royal Danish Academy of Sciences and Letters and Chief Scientist at the Danish National Center for AI in Society (CAISA).
