The major focus of my research is on the interface between plants and their environment. Particularly I am interested to understand the physiological responses of plants to their abiotic and biotic environment and the role of plants in the functioning of ecosystems.
I have had extensive research experience in plant ecophysiology and biogeochemistry, with research relating to processes operating at leaf, whole plant and ecosystem scales. My work has recently focused on the process-based investigation of carbon balance, nutrient cycling and fluxes of greenhouse gases in forest ecosystems and the adaptation of trees to environmental stresses. My contribution to this field has been to use physiological and ecological measures to increase our understanding of ecosystem function, with improved process understanding and model development as a goal.
