Organisation or Individual Expertise:
My research centres on the impacts of agriculture on the environment, in particular nitrogen pollution and the mitigation of greenhouse gas emissions through crop management and land use change (Ecophysiology and Soil Science). My current research includes the modelling of nitrous oxide flux and soil respiration from grasslands and cereal crops in Ireland to understand how future climate change may affect these soil processes. A particular focus of my present research is the potential of legume crops in Europe to reduce N pollution and increase biodiversity. Previous research interests are wide and I have published on assimilate distribution in plants in relation to cell specialisation and also metabolic aspects of chloroplast symbiosis. Current Research and Research Opportunities My present research students are involved in measurements of N fixation, leaching and nitrous oxide flux through both the FP7 Legumes Futures project and research contracts with Teagasc and the Department of Agriculture. I have supervised 9 PhD projects both national and international, over ten MSc projects and approx. 40 undergraduate research projects.
