Postdoctoral Research Fellow

My main research interest is environmental science, since it provides me with the ability to understand environmental problems and how these affect the quality of human life. As a consequence, my research aims to make a genuine contribution to the sustainable development of society and an improved understanding of human-natural environment interactions. My prior experience is in soil pollution, fractured media characterization and geological storage of CO2. For the last years I have been working in surface monitoring of CO2 storage sites as part of my doctoral thesis.

The topic of my post-doctoral project deals with radon monitoring and hazard prediction. It is financed by the Irish Research Council under the Enterprise Partnership Scheme 2015 (#LoveIrishResearch), and co-financed by the Geological Survey of Ireland. This new research project will build upon previous efforts of radon monitoring in Ireland to construct a high-resolution radon hazard map. This map will help to inform when prevention and remediation measures are necessary, reducing the radon exposure of the population.
