    Iain Duffy, Ph.D.

    Associate Professor

    Dr Duffy is an Associate Professor of Biology and has been a full-time teaching member of the Saint Leo Community since 2005. Prior to SLU Dr Duffy had worked in science research. First, performing research on liver drug detoxifying enzymes, and their effects on bilirubin and jaundice. Examining potential functions in diseases such as Gilbert’s Syndrome and Crigler-Najjar Syndrome. This was followed by several years working in pharmacokinetics as an analyst with companies performing clinical drug trials for the pharmaceutical industry.

    Dr Duffy has an Honours Degree in Microbiology from Coláiste na hOllscoile, Corcaigh [UCC], Ireland. His undergraduate dissertation was “Construction of Lactococcus lactis strains with increased bacteriophage resistance levels using conjugal phage resistance plasmids”.
    For his PhD in Molecular Virology from The Queen’s University of Belfast, Northern Ireland, Dr Duffy studied measles virus. A major part of this research was the use of reverse genetics to rescue mutant measles virus containing potentially lethal neurovirulence mutations, and the subsequent study of their pathogenicity.

    Upon completion of his PhD Dr Duffy arrived in Tampa in 2000 to commence research at the H. Lee Moffitt Cancer Center. Initially examining the MHC class I presentation of HIV proteins, followed by the role of cell cyclins, such as cyclin G2. A major part of his research involved constructing viral vectors expressing RhoB and exploring their potential use in the treatment of tumors.

    Dr Duffy’s current research interests include the isolation and characterization of bacteriophage and their potential roles in phage therapy. He also studies antibiotic resistance in bacteria. He is currently collaborating in cancer research, namely tumor angiogenesis, and the role played by ALK-1 and Endoglin proteins.
