Research interestsMy research focuses on plant-soil interactions, and in particular how changes in plant communities influence ecosystem processes such as carbon and nutrient cycling. Examples of recent research include looking at how broom invasion alters soil processes and biota, how changes in plant species evenness and spatial arrangement modifies above and belowground processes, and linking plant traits to soil processes in grassland ecosystems.
