Dr. Sibel Eker is a senior research scholar at the Energy, Climate and Environment program of the International Institute for Applied Systems Analysis (IIASA). Her interdisciplinary research profile combines systems analysis and engineering, decision sciences, and social sciences. Her work brings a systems thinking and uncertainty focus to climate change and sustainability problems with model-based approaches. Complementing her academic experience, she has worked with several stakeholders and policy actors such as the UK Department for Business, Energy, and Industrial Strategy, the World Bank, the European Institute of Innovation and Technology (EIT)-Climate Knowledge and Innovation Community (KIC), as well as other governmental and private organizations.
Her current research interests center around the drivers and implications of demand-side climate change mitigation, sustainable diets, and co-production of mitigation and sustainability scenarios through simple integrated assessment models. Eker has had leading roles in related European and global research projects.
Eker is a selected member of the Global Young Academy, where she co-led the Scientific Excellence Working Group between 2022 and 2024. She is also a Lead Author of the United Nations Environment Programme (UNEP) Global Environment Outlook (GEO-7). She taught system dynamics modeling at Radboud University in The Netherlands, first as an assistant, and then as an associate professor between 2021 and 2025. She was earlier a senior researcher and modeler at Climate Interactive, working on the development of the C-ROADSand En-ROADS climate policy simulators.
Eker obtained her PhD degree in 2016 from Delft University of Technology in The Netherlands, with a focus on dealing with uncertainties in the Dutch natural gas sector. Prior to joining IIASA in 2017, she worked at University College London on integrated decision making in housing, energy, and wellbeing; and at Delft University of Technology on the resilience of the transport network in Bangladesh.
