Stefan Thurner

Stefan Thurner (born 1969) is an Austrian physicist and complexity scientist. He heads the Section for Science of Complex Systems at the Medical University of Vienna and is a co-founder and the president of the Complexity Science Hub (CSH). Thurner also serves as an external professor at the Santa Fe Institute .

His research focuses on extending statistical mechanics to networked complex systems out of equilibrium, with applications to the dynamics and phase transitions of social, biological, and economic systems. Notable contributions include a theory for systems out-of-equilibrium, stress-testing of healthcare systems, agent-based modelling of systemic risk in supply chains and financial networks, and the quantification of resilience. He authored Introduction to the Theory of Complex Systems, a textbook on complex systems.

Thurner has received awards including Austrian Scientist of the Year 2017 and the Paul Watzlawick Ring of Honor (2021).
