Sönke Zaehle

Prof. Dr. Sönke Zaehle is a leading biogeochemical researcher at the Max Planck Institute for Biogeochemistry, directing the Department of Biogeochemical Signals. He also holds an Honorary Professorship at the Faculty of Chemistry and Geosciences, Friedrich Schiller University Jena. His work spans terrestrial biosphere modeling, nutrient cycling, and climate system interactions.

Education

• MSc in Environmental Sciences, University of East Anglia (2000-2001)
• Doctoral studies, University of Potsdam / Potsdam Institute for Climate Impact Research (2001-2005)
• Geoecology, Technical University of Braunschweig (1997-2000)

Research Focus
Zaehle integrates terrestrial biosphere models (e.g., QUINCY) with observational data to study carbon-nitrogen-phosphorus coupling, climate feedbacks, and land-atmosphere exchange. His work addresses global change impacts on ecosystems, model-data synthesis, and uncertainty quantification in biogeochemical cycles.

Article Trends
Recent publications emphasize climate extremes, nutrient cycling in Earth System Models (CMIP6, MAGICC), and Amazon carbon dynamics. Themes include model development, remote sensing integration, and climate-carbon-nitrogen interactions under anthropogenic forcing.

Scientific Leadership
Zaehle contributes to international initiatives as a Lead Author for the IPCC 6th Assessment Report and Associate Editor of Biogeosciences. He also advises New Phytologist and participates in councils like the Minerva-Weitzmann Committee.

Teaching & Community Engagement
He teaches Klimatologie und Klimawandel and Globale Umweltmodellierung at Friedrich Schiller University. He mentors through the IMPRS for Global Biogeochemical Cycles and collaborates with institutions like the Michael Stifel Centre Jena for data-driven science.
