Biography

I graduated from UCD in 1997 with a first class honours degree in Animal Science and later with a Ph.D in 2002. Following this I took up a research position at the Teagasc Dairy Research Centre, Moorepark, Co. Cork. I have lectured at UCD in the areas of animal nutrition and fertility since 2003. I am leading ongoing research projects examining the role of strategic manipulation of cattle diets on improving (i) the nutraceutical composition of beef, and (ii) the reproductive performance and health status of cattle (Funded by DAFF RSFP) (iii) The biological control of energetic efficiency and ruminal methane production in beef cattle (Funded by DAFF RSFP). I am also a task leader on three other DAFF RSFP projects. I am currently collaborating with colleagues at the Teagasc Research Centres at Athenry, Grange and Moorepark as well as colleagues at the the National University of Ireland, Galway, Royal Veterinary College, London, University of York, UK and Agriculture and Agri-Food Canada. These research projects are funded by DAF RSFP, commercial companies, The Welcome Trust and the Teagasc Walsh Fellowship Scheme. I am currently the principle supervisor of 17 Ph.D and 3 masters degree students and have successfully supervised the theses of three Ph.D. and three Masters degree students. I have recently completed postgraduate diploma courses in both Statistics (2005) and Molecular Medicine (2006) at Trinity College Dublin. I am a council member of both the Irish Agricultural Research Forum and the British Society of Animal Science and am a member of the Teagasc Beef Commodity Group and the DAFF Beef Task Force.
