Fabian Wagner

Fabian Wagner is a senior research scholar at the International Institute for Applied Systems Analysis (IIASA), with adjunct faculty status at the Technical University of Vienna and Associate Faculty affiliation at the Complexity Science Hub (CSH) Vienna. He previously served as the Gerhard R. Andlinger Visiting Professor for Energy and the Environment at Princeton University’s Andlinger Center and Woodrow Wilson School during 2014–2016.

Education:

• PhD in Theoretical Physics, University of Cambridge (UK)
• Master’s in Mathematics, University of Cambridge (UK)
• Master’s in History and Philosophy of Science, University of Cambridge (UK)

Fabian’s research centers on sustainability science, particularly the interconnections between energy, water, climate, air, health, and sustainable development goals (SDGs). He employs advanced methodologies including network analysis, deep learning, optimization, and risk modeling. His current focus includes urban metabolism, resilience, climate-economy modeling, and integration of process-based and input-output analysis techniques. His interdisciplinary approach bridges physical, environmental, and socio-economic systems.

The analysis of his publications from 2010 to 2025 reveals a consistent trajectory in sustainability and systems modeling, with increasing integration of data-driven methods like deep learning and network science. His work spans climate policy, urban sustainability, and global environmental change, often addressing complex, multi-scale challenges through integrated modeling frameworks.

Scientific Awards:

• Cambridge University’s J.T. Knight’s Prize in Mathematics (1998)

Fabian has advised interdisciplinary research initiatives and has consulted for major international organizations including the United Nations Framework Convention on Climate Change (UNFCCC) and the International Monetary Fund (IMF), indicating involvement in high-level policy-oriented research and advisory roles. While specific grants are not listed, his long-standing position at IIASA and collaborations with global institutions suggest sustained funding and leadership in large-scale research projects.

He is actively involved in interdisciplinary research teams at IIASA, CSH Vienna, and through his affiliations with Princeton and TU Vienna, contributing to collaborative efforts in complexity science, energy systems, and sustainable development.
