Science and policy must work together to achieve a sustainable future for humanity.
Stefan Thurner joined IIASA on Jan 1 2010, and is currently affiliated with the Advanced Systems Analysis (ASA) Program. His research focus is on dynamics and control of complex networked systems, in particular the resilience and systemic risk of financial markets and economic networks. He pioneers the use of large-scale, data-driven agent based models for policy implications. He is actively engaged in several big-data analytic initiatives. He is full professor for Science of Complex Systems at the Medical University of Vienna, where he chairs Section for Science of Complex Systems. Since 2007 he has been an external professor at the Santa Fe Institute, since 2015 he has been the president of the Complexity Science Hub Vienna, and since 2016 a distingiushed visiting professor at Nanyang Technological University in Singapore.
Prof. Thurner obtained a PhD in theoretical physics from the Technical University of Vienna (1995), and a PhD in economics from the University of Vienna (2001). Following on from postdoc positions at Humboldt University, Berlin and Boston University, he joined the faculty of the University of Vienna in 1999 and later the Medical University. He holds a habilitation in theoretical physics (2001). Since 1995, Prof. Thurner has published approximately 200 scientific articles covering areas of fundamental physics, mathematics, complex systems, life sciences, economics and social sciences. His work has received some media interest, including the New York Times, BBC World, Nature, New Scientist, and Physics World and has been featured in around 500 newspaper, radio and television reports. He holds 2 patents.
