Research Experience

Funding; I have been the lead-DIT academic on a successful application to formulate an Enterprise Ireland/Irish Meat Industry funded Meat Technology Centre in a Teagasc DIT UCC consortium. The award was 7 million euro. In addition I have been awarded personal grants of over €480,000 between  FIRM (x2), EU:ProSafeBeef, Manchester Innovations, BBSRC, EU: BAP and  EU:BRIDGE programs.

Research: Supervised research students up to level 10 and have collaborations nationally and internationally. Presented my work at a number of international conferences.  

Scholarly Activity

  • Chairman and was recently elected Fellow of The Institute of Biology of Ireland and member of the Institute of Food Science & Technology of Ireland.
  • Appointed Program-Coordinator of Human Nutrition while at IT Sligo
