In the Shao EcoLab we study how soil microorganisms shape the carbon and nutrient cycles of whole ecosystems. We build process-based models in which microbes are active players rather than hidden inside the equations, and combine them with experimental and observational data to address questions that experiments alone cannot resolve. We work across peatlands, forests, and agricultural systems, in collaboration with field and laboratory research groups.
Models of the Earth system usually treat soil biology as a passive modifier of geochemistry. Our work starts from the opposite premise: that microbial and fungal activity often sets the rate, and that models which leave it implicit get the wrong answer. Representing that biology faithfully means working across scales that run from traits measured on a single fungal isolate to fluxes integrated over a landscape, and across disciplines that run from microbial ecology to soil geochemistry to numerical modeling. Meeting that challenge is what makes it possible to predict how ecosystems will respond to climate change and to management.
