Biography

I teach in the field of tectonics, and my research involves applying geochronology and isotope geochemistry to various problems in the geosciences. These research interests include 'sedimentary provenance' - applying isotopic analyses to sand grains to characterise ancient drainage systems in the geological record and the erosional history of mountain belts, and applying novel geochronological approaches to minerals that are challenging to date by the U-Pb method (e.g. carbonates, apatite) to quantifying the timing and rates of tectonic processes such as orogenesis (mountain building) and exhumation. Education and Academic Career: 1996 B.Sc. Geology (First Class Hons), University College Dublin. 2001 Ph.D. Geology, University College Dublin. 2001-2003 Temporary Lecturer, Department of Geology, Trinity College Dublin. 2003-2005 Post-doctoral researcher, University of Geneva, Switzerland. 2005-2014 Assistant Professor, Department of Geology, Trinity College Dublin. 2012 Elected Fellow of Trinity College Dublin. 2014-2019 Associate Professor, Department of Geology, Trinity College Dublin. 2019-present Professor in Geology, Department of Geology, Trinity College Dublin. Significant academic roles: 2022-present Deputy Director of the SFI Research Centre in Applied Geosciences (iCRAG). 2017-2021 Head of Geology, Department of Geology, Trinity College Dublin.

Research Interests

Description Of Research Interests

My research involves applying geochronology and isotope geochemistry to a diverse series of questions in the geosciences. It is based mainly around novel method development and applications of laser-ablation (LA) ICP-MS techniques to various geoscience problems, including isotopic dating of sedimentation, sedimentary provenance studies and quantifying the timing and rates of tectonic processes such as mountain building and exhumation. My research group has pioneered U-Pb dating of apatite by the LA-ICP-MS method, and integrating it with both apatite fission-track analysis and apatite trace-element geochemistry to yield protolith compositions in provenance studies. This work was developed in an SFI Investigators Programme grant on applying detrital apatite as a provenance indicator in systems. We have extended our LA-ICP-MS U-Pb dating approaches to undertaking rapid and routine geochronology of U-bearing minerals with appreciable common Pb. We now routinely undertake multi-proxy provenance studies based on U-Pb dating of accessory heavy minerals (e.g. apatite, rutile, titanite, zircon and monazite), in collaboration with leading international research groups and also in Ireland within the SFI iCRAG research centre. Recent research has focussed on developing LA-ICPMS mapping. A key novel development is our U-Pb age mapping approach to dating calcite and zircon. This method is based on selection and pooling of pixels from 2-D elemental and isotopic ratio maps, and is a particularly powerful technique for targeting subdomains in samples with complex geological histories. The U-Pb calcite dating work is funded by an SFI Investigators Program award and has important and novel applications. These include constraining the timing of mineralization in the world-class Irish Zn-Pb mineral province, dating of syn-tectonic carbonate veins in carbonate sequences in orogenic belts, or direct dating of carbonates for key time intervals in Earth history such as Neoproterozoic 'Snowball Earth' glacial episodes.
