Read how IIASA works with research partners across the globe to deliver world-class research.
Science and policy must work together to achieve a sustainable future for humanity.
Sebastian Poledna is a research scholar at the International Institute for Applied Systems Analysis (IIASA), and at the Section for Science of Complex Systems at the Medical University of Vienna. At IIASA, he is a member of both IIASA’s Risk and Resilience (RISK) and Advanced Systems Analysis (ASA) programs.
Mr. (MMag.) Poledna holds double degrees in physics and economics and has worked as a practitioner in risk management at one of the largest European banks for almost a decade. He conducted his PhD in physics (econophysics) at the University of Vienna, where he is expected to defend it within the next few months.
The focus of his research is on financial networks, systemic risk, financial stability and agent-based modeling, where he has recently published several papers. He did his PhD as part of the EC FP7 project CRISIS, which aimed to build a new model of the economy and financial system based on how people and institutions actually behave. At CRISIS, he helped to develop the CRISIS macro-financial agent-based model.
