Biography

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.

Research

Research Interests

My research 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.

Due to their structural diversity, biological specificity and chemical stability in the environment, lipid molecules and their diagenetic products (geolipids) are the most useful molecular fossils across the geologic record.
 
To date I have worked on a number of questions and projects in the marine sciences, soil sciences, environmental sciences, palaeontology, palaeobiology, geobiology, microbial ecology and astrobiology. The current projects I work on include:

- palaeobiological and palaeoenvironmental information preserved in organic matter bound within non-skeletal carbonates e.g. ooids, tufa, pisoids

- understanding how vertebrate soft tissues preserve at the molecular level and what diagnostic biomolecular information is preserved 

- reconstruction of vegetation and environmental change from ancient peat and paleosols

- identifying organic biosignatures on Mars using analogue pyrolysis GC-MS experiments

- understanding the microbial processes in mineral precipitation, especially carbonates of geobiological interest

- using organic molecules to study the source and extent of human contamination of the environment, especially faecal contamination, petroleum spills and persistent organic pollutants
