Oliver Fricko joined IIASA in 2012. He is a research scholar in the Integrated Assessment and Climate Change (IACC) Research Group of the Energy, Climate, and Environment Program.

He is one of the core developers of the Model for Energy Supply Strategy Alternatives and their General Environmental Impact (MESSAGEix) framework and a central modeler of IACC. He is involved in numerous multi-model inter-comparison studies, including the Shared Socioeconomic Pathways (SSPs), the Energy Modeling Forum (EMF-30 and EMF-33), as well as projects funded by the European Commission (ADVANCE, CD-Links, ENGAGE, and ELEVATE). He also acts as a technical advisor to numerous other projects.

He has co-authored close to 50 publications that have been cited over 8,000 times and has an h-index of 30. He was acknowledged as a Highly Cited Researcher by Clarivate in 2020, 2021, 2022, and 2023.

As the lead global energy modeler, Fricko maintains and coordinates the development of the IACC global energy model (MESSAGEix-GLOBIOM). Currently, he is coordinating/implementing the development of updated SSP scenarios within IACC.

Fricko developed and maintains the soft-linkage between MESSAGEix and the IIASA Global Biosphere Management Model (GLOBIOM) and is currently integrating information on non-CO2 greenhouse gas and pollutant emissions from the Greenhouse Gas and Air Pollution Interactions and Synergies (GAINS) model into MESSAGEix. He developed an approach for incorporating national policies in the global energy model, for example, Nationally Determined Contributions (NDCs) or the net-zero targets, and has enhanced the modeling framework to account for energy system wide water requirements.

Fricko has collaborated with various institutions to develop and train national capacities. This includes several institutions from India such as the National Institution for Transforming India (NITI-Aayog) and TERI-University. Recently, he coordinated and partly implemented IIASA related work within the Strategic Partnerships for the Implementation of the Paris Agreement (SPIPA)-India project, which aims to support EU-India collaboration on the development of modeling capacities to improve the quality of modeling tools and integrated modeling analysis frameworks developed by modeling teams in India.
