Sibel Eker

Senior Research Scholar

Sustainable Service Systems Research Group

Energy, Climate, and Environment Program


Sibel Eker is a senior research scholar in the Sustainable Service Systems Research Group of the IIASA Energy, Climate, and Environment Program. 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, such as the FeliX model. Eker has had leading roles in related European research consortia, including the ongoing WorldTrans and CHOICE projects, and she is the PI of LOW-AI.

Eker is a selected member of the Global Young Academy where she co-leads the Scientific Excellence Working Group. She is also a Lead Author in the United Nations Environment Programme (UNEP) Global Environment Outlook (GEO-7), as well as an editorial board member of Humanities and Social Sciences Communications and Mitigation and Adaptation Strategies for Global Change. She teaches system dynamics modeling at Nijmegen School of Management and as part of the European Master in System Dynamics.

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.
