Biography

I graduated from UCD in 2001 with a first class honours degree in Animal Science and later with a PhD in 2005. Following a short period involved in the organization of the International Grassland Congress hosted in Dublin in 2005 I joined the lecturing staff in UCD where I currently lecture ruminant nutrition and sheep husbandry.
My main areas of research are;
reduction of enteric methane emissions by ruminants;
increasing nitrogen capture in the rumen;
fatty acid profiles in perennial ryegrass varieties;
grazing management for spring calving dairy herds
the use of a rumen simulation system to model the effects of various dietary additives on rumen function.
nutrition during late pregnancy and early lactation nutrition of the ewe.
