I am interested in geochemically and temporally characterising significant processes and events in Earth history. My current research projects span the present day into the Archean. Some of these projects also deal with formation of economic mineral deposits and geosphere-biosphere-hydrosphere-atmosphere interactions.
The following are examples of my current research topics:
- Production, transport and accumulation of radon: Ireland has some of the highest radon levels in Europe and the eighth highest average indoor concentration in the world. I am interested in developing novel methodological advancements in radon-related research to better understand the factors controlling the sources and distribution of radon in both natural and built environments. I am academic mentor of a Post-Doctoral Research Fellow (Javier Elio) at TCD working in this theme.
- Cold-water corals as environmental archives of the deep oceans: Biominerals have the potential to act as high-resolution proxies for environmental change. Cold-water corals (e.g. Lophelia pertusa) form a significant biomass is the North Atlantic offshore Ireland and represent an under-explored potential as a high-resolution proxy for environmental and climate change spanning the present day to Miocene.
- Geochemistry of the contemporary environment: Elemental and isotopic analyses of rock, soil, plants and biominerals (e.g. teeth and bones) have the potential to inform us about natural processes such as rock weathering and soil formation, interaction between terrestrial and marine reservoirs, animal and human migration and environmental effects of anthropogenic activities.
- Evolution of the early Earth: I am currently working on geochemistry and geochronology of Archean rocks from Mauritania (West African Craton), NE Scotland (Atlantic Craton) and India (Singhbhum Craton) to gain a better understanding of processes operating in the early Earth.
- The nature and timing of mineralisation in relation to magmatic and tectonic processes: I am interested in providing absolute age constraints on economically significant mineralisation events. Current projects include Archean Au mineralisation in Mauritania, Palaeoproterozoic Cu-Mo porphyry deposits in Namibia and Ordovician Au-Cu-Zn-Pb mineralisation in SE Ireland.
