Research Scholar

Integrated Assessment and Climate Change Research Group

Energy, Climate, and Environment Program


Daniel Huppmann coordinates the research theme 'Scenario Services and Scientific Software' in the IIASA Energy, Climate, and Environment (ECE) Program. With his team, he develops tools and software packages for scenario ensemble compilation, validation, analysis, and dissemination in line with best-practice of scientific-software development and FAIR data management. These tools are used within numerous Horizon 2020 projects (e.g., European Climate and Energy Modelling Forum (ECEMF) and openENTRANCE (Open Energy Transition Analyses for a Low-carbon Economy)) and other research activities, as well as in the contributions of Working Group 3 to the ongoing Intergovernmental Panel on Climate Change (IPCC) Sixth Assessment Report (AR6).

Huppmann was an author of the 2018 IPCC Special Report on Global Warming of 1.5 °C (SR15). His responsibility for the SR1.5 was the compilation of an ensemble of quantitative scenarios (Chapter 2) and the assessment of the interaction across different Sustainable Development Goals (SDGs, Chapter 5).

In parallel to his contribution to the IPCC, he was the lead developer of the energy system and integrated assessment framework MESSAGEix, an open-source platform for integrated and cross-cutting modeling. This system underpins the MESSAGEix-GLOBIOM Integrated Assessment Model, which is used as the core modeling tool in the ECE Program to explore national and global transformation strategies in the context of climate change and their linkages to a range of sustainable development objectives.

Before joining IIASA in October 2015, Huppmann was awarded a Postdoctoral Fellowship at Johns Hopkins University, Baltimore, USA, where he worked in the Civil Engineering Department. During this time, he was also affiliated as a Visiting Fellow at the think-tank Resources for the Future
(RFF) in Washington D.C. Before his research sojourn in the US, he worked at the Department of Energy-Transportation-Environment at the German Institute for Economic Research (DIW Berlin), Germany.

Huppmann graduated with a doctorate in economics from Technical University Berlin after successfully completing the structured PhD program at DIW Berlin, defending his dissertation summa cum laude in June 2014. He also studied Mathematics at the Vienna University of Technology, where he earned an MSc degree in 2010.
