School of Earth Sciences
I earned my PhD from DCU in 2013, in environmental and organic geochemistry. My PhD project was funded by the Irish Research Council Postgraduate Scholarship program and was supervised by Dr. Brian Kelleher (DCU) and Dr. Chris Allen (QUB). I investigated recently discovered marine cold seep features in Irish waters, as well as marine organic matter composition and fate in the Irish Sea.
In 2014 I was awarded a Marie Curie Actions Program-Irish Research Council COFUND Postdoctoral Fellowship (ELEVATE). This fellowship is in collaboration with Prof. Roger Summons at Massachusetts Institute of Technology and Prof. Frank McDermott in the National Centre for Isotope Geochemistry in University College Dublin.
I recently arrived back from MIT, where I spent 2 years, and am completing the final phase the fellowship in the School of Earth Sciences in UCD. In August 2017, I was awarded an additional 8 months funding from the Irish Research Council to extend the fellowship to mid-2018.

interests involve the application of organic molecular markers - also often called biomarkers - to address a range of questions in
environmental and Earth sciences. In questions relating to Earth history, certain organic molecules can act as molecular fossils and provide incredible insight into biological and environmental change over timescales stretching back hundreds of millions of years.
