Soil Biogeochemistry Laboratory

Welcome to the Soil Biogeochemistry Laboratory

Soils connect the atmosphere, hydrosphere, lithosphere, and biosphere. They sustain life on Earth and underpin ecosystem services from climate regulation and nutrient cycling to food production and pollutant attenuation. Yet these services are increasingly under pressure from global change.

At the Soil Biogeochemistry Laboratory, we investigate soil redox processes—the electron transfer reactions that control the cycling of carbon, nutrients, and contaminants. Our goal is to achieve a molecular- and micron-scale understanding of these processes and determine how they contribute to shaping ecosystem functions under a changing climate.

We combine field studies, laboratory experiments, and modeling to unravel redox-dependent biogeochemical fluxes across space and time. Our work draws on approaches from environmental chemistry, microbiology, soil science, and hydrology, and we develop novel analytical tools to quantify redox reactions and their associated energy transformations.

Through this research, we aim to improve the representation of soils in biogeochemical models, enable more accurate predictions of element cycling, and inform sustainable soil management practices that protect soil resources while reducing environmental impacts.
