Markus Maisch

Markus Maisch is a Researcher at the Department of Geosciences within the Faculty of Mathematics and Natural Sciences at the University of Tübingen. His work combines experimental environmental geochemistry with technical infrastructure development for environmental monitoring and isotope analyses, focusing on natural processes in water and carbon cycles.

After studying geoecology at the University of Tübingen, he specialized in geomicrobiology, investigating biogeochemical cycles in sediments, soils, and rhizosphere environments. His research encompasses microbial iron oxidation, phototrophic Fe(II) oxidation, and analysis of iron/nitrogen processes in rice paddies and marine systems.

As laboratory head in the Climatology and Biosphere research group, he develops long-term climate impact monitoring concepts, explores nature-based CO₂ removal strategies like enhanced weathering, and studies soil carbon sequestration. He contributes to interdisciplinary teaching through projects like #ZukunftslaborErde, connecting science with societal challenges.

His 15 most recent publications (2025-2020) demonstrate consistent focus on iron cycling mechanisms across diverse environments (lakes, permafrost, marine systems, soils), combining microbial ecology with geochemical process analysis. Key methodologies include Mössbauer spectroscopy, stable isotopes, and flow-through experiments.

Markus Maisch leads the Climatology and Biosphere working group at the University of Tübingen, collaborating with researchers like Kira Rehfeld, Armelle Ballian, and Jean-Philippe Baudouin. His team employs experimental systems like Redoxtrons to simulate redox processes in capillary fringes.
