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.
