My research interests focus on carbon and nutrient (especially nitrogen) cycling in ecosystems. In particular, I am interested in the mechanisms controlling carbon storage in soils and how plants and soil microbes interact in the nitrogen cycle. Most of my work has been in temperate grassland or polar ecosystems. Much of this is associated with climate change, such as effects of elevated carbon dioxide concentrations, increasing temperatures or extreme weather conditions. My principal expertise is in the use of stable- and radio-isotopes to characterise fluxes in plant-soil-atmosphere systems.
