I am an interdisciplinary researcher in renewable energy and environmental science, based in the Climate Policy Group at ETH Zürich’s Department of Environmental Systems Science. My research is on the global transition to a 100% clean and renewable energy system, and the technical, economic and policy barriers on the way to that goal.

In the course of my work I created and lead development of the open-source energy system modelling tool Calliope. I am also the creator and lead developer of the Renewables.ninja platform to simulate wind and solar power plants worldwide. I am a member of the Open Energy Modelling Initiative, which promotes openness and transparency in energy system modelling, and of the Open Power System Data project, which provides a free and open data platform for power system modelling.

You can contact me by email. I am always interested to speak to enthusiastic students looking for thesis projects or research experience. Get in touch by email with a CV and some detail on your research interests.
