Biography
Sebastian Poledna is the leader of the Exploratory Modeling of Human-natural Systems (EM) Research Group of the IIASA Advancing Systems Analysis Program.His scientific interests include new approaches to macroeconomics, the impact of climate change on socioeconomic systems, the systemic risk of various complex systems, and financial regulation.
He holds double degrees in physics (2005-2011) and in economics and business administration (1999-2003), and has worked as a practitioner in risk management at one of the largest European banks for almost a decade (2007-2015). He obtained his PhD in physics at the University of Vienna in 2016.
Poledna first joined IIASA as a research scholar in the former IIASA Advanced Systems Analysis and Risk and Resilience programs in 2015. In January 2021, he was appointed research group leader of the EM Research Group. The EM Research Group currently has 35+ scientists whose aim is to produce methodological advances that will underpin future IIASA research.
