My research focuses on the interactions between plants and the environment, particularly in the Arctic, northern boreal and upland ecosystems. I study the impacts of climate change (warming, extreme events, snow regime change, precipitation), UV-B radiation and pollution on ecosystem structure and function. I'm interested in the impacts on biodiversity, on cycling of carbon, nitrogen and phosphorus, and the consequences for feedback to climate (ecosystem carbon balance). I also aim to understand how responses observed at the vegetation/ecosystem level are driven by individual plant, root and leaf responses. Other interests include more applied fields such as understanding nutrient acquisition for sustainable agriculture.
