Dr. Duffy was born in Dundee, Scotland. Upon leaving secondary school he began work as a researcher in the Biochemistry Department of Dundee University, looking at drug detoxifying enzymes in the liver. This was followed by employment as an Analyst in Biopharmaceutics at Drug Development [Scotland] Ltd., based in Ninewells Hospital, Dundee, Scotland and then The Institute of Biopharmaceutics Ltd, based in Athlone, Ireland. He then decided to pursue an undergraduate degree in microbiology at UCC in Cork, Ireland with a research dissertation entitled: Construction and Characterisation of Novel Strains of phage resistant Lactococcus lactis  via conjugation of plasmids. This was followed by a PhD at QUB, Belfast based on the Analysis and Characterization of Measles Virus Glycoproteins.
