Research Interests: Initially my research interests focused on understanding radiation effects on mammalian cells, principally through the examination of chromosome rearrangements. On moving to Moorepark my activities centred on the enumeration, identification and development of bifidobacteria and pedioccoci as probiotics This work led to the discovery of new Bifidobacterium species with improved tolerance to air, the development of spray dried milk powders to deliver probiotics and a detailed understanding of colonising bifidobacteria in the piglet intestine.

More recently I have concentrated on the production of health promoting bioactive peptides from milk protein substrates hydrolysed by novel microbial fermentations.
