Christoph Müller

Christoph Müller is a Professor of Experimental Plant Ecology at Justus Liebig University Giessen (since 2009) and a Visiting Professor at University College Dublin's School of Biology and Environmental Science (since 2007). His work bridges soil science, plant ecology, and climate change biogeochemistry.

• PhD in Soil Science (Lincoln University, NZ, 1995)
• MSc in Soil Water Management (University of Reading, 1991)
• Diploma in Horticulture (FH, 1990)

Research centers on climate change impacts on terrestrial ecosystems, focusing on elemental cycles and trace gas production in soils. He pioneered 15N/13C isotope tracing to quantify gross nitrogen transformations and developed Ntrace software for analyzing these processes. His landmark Giessen FACE experiment (20+ years) demonstrates how elevated CO2 alters rhizosphere microbiomes and nutrient dynamics.

Recent publications (2021-2023) reveal mechanisms linking soil clay minerals to nitrogen cycling, quantify DNRA patterns across ecosystems, and explore biochar-nitrapyrin synergies for emission reduction. Grants from EPA Ireland and Department of Agriculture Ireland support his work on greenhouse gas mitigation and sustainable fertilization.

Collaborations span institutions like UCD, with co-authors including Gerald Moser, Daniela Senkbeil, and Lea Meng. Current editorial roles involve European Journal of Soil Science and Frontiers in Terrestrial Microbiology. His methodology integrates stable isotope tracing, metabarcoding, and process-based modeling to unravel soil-plant-microbe interactions.
