My research broadly seeks to quantify and better understand how plants and soil microbes influence energy flow and nutrient cycling in terrestrial ecosystems in the wake of human-accelerated environmental change. Of particular interest is the degree to which plant-microbial interactions in soils influence feedbacks to regional and global change through their effects on ecosystem carbon storage and nitrogen and phosphorus retention.
- Coupling of plant and microbial productivity
- Species effects on nutrient cycling
- Plant-soil-microbial feedbacks to global change
