on the road.

I'm a researcher working at the intersection of energy, economic and environmental systems — modeling how policies, technologies, and people shape the path to climate neutrality. I build models across scales, from single buildings to global economies, and I'm a big believer in open-source tools, agent-based thinking, and AI as new research infrastructure.

Senior Researcher

Almost six years at the German Fraunhofer Institute for Systems and Innovation Research (tenured in Oct. 2022). Led work packages in EU Horizon projects (ECEMF, newTRENDs, ENEFIRST) and served as sectoral modeller for German federal energy-transition policy assessments including the UBA Treibhausgas-Projektionen. Shaped the FLEX and RENDER modeling suites, and released Melodie. The most productive stretch of papers and reports so far.

Visiting Researcher

First time at ISI as a visiting researcher — bridging from the PhD into a German energy-policy research context. The agent-based emission trading model from the PhD landed in European Journal of Operational Research.

Where the road begins.

Beijing, autumn 2009. From there to here is 16 years — first as a student, then as a researcher building models, writing papers, and finding many great collaborators along the way.
