Research Interests

I have a keen interest in all aspects of farming research, demonstrated by my past and current involvements in research projects on biofuels, break crops, rotations and protein in which I have secured over €1.25 million worth of external funding. In my previous role as coordinator of the OptiBC RSF project I was co-supervisor of a PhD looking into the health benefits of rapeseed oil and this is an area of great interest to me. I have initiated contact with researchers from other institutions and hope to be involved in future studies into the use of native protein sources as a replacement for imported soya in animal feed.

I am constantly looking for opportunities to further my knowledge and experience through participation in further studies in all aspects of agriculture, specifically, rotations, break crops, sustainability and biodiversity.

I aim to develop my professional skills continuously and would be very eager to enrol in any course which may be suitable to help in the delivery of the Agricultural Science course. Specifically, I am interested in pursuing continuing professional development in blended learning; student supervision; and general trends in higher education to inform my lecturing work.

Engagement and Collaboration

With 12 years experience at Teagasc I have gained numerous contacts both within Teagasc and the greater agricultural industry. Research was conducted with the aim of delivering best possible expertise to the wider farming community, while constantly considering industry engagement and how it develops.

Some collaborative projects I was involved in include-

  • 2006 – 2009: DAFM RSF project entitled Feasibility of pellet production from energy crops and agricultural residues.
  • 2010 - 2013: ERANET Futurebiotec project entitled Future low emission biomass combustion systems.
  • 2013 - 2014: DAFM RSF project entitled CropQuest: Broad acre break crop options for Irish farmers.
  • 2015 – 2019: DAFM RSF project entitled VICCI: Virtual Irish Centre for Crop Improvements. As part of this large €3 million project I led a task with a budget of approx. €200k in association with the University of Reading looking at Bean breeding for Irish conditions.
  • 2015: I was involved with an unsuccessful pan European proposal to ISIB 2 on legumes.
  • 2016: I was involved in an unsuccessful submission under FP7 involving 15 European partners on protein crops.
  • 2016 - 2020 I wrote and was co-ordinator on a €1 million project from the DAFM RSF 2015 call, with WIT and UCD entitled Opti-BC: optimising break crop agronomy in Irish conditions.
  • 2017: I am involved in a H2020 proposal with 12 European partners on knowledge transfer in rotations and break crops.
