Dr Stuart Hamilton is an NHMRC Early Career Research Fellow and Postdoctoral Research Scientist at the Virology Research Laboratory, SEALS Microbiology, Prince of Wales Hospital and School of Women’s and Children’s Health, University of New South Wales. He completed his Bachelor of Science degree at UNSW with a double major in Molecular Biology/Medical Microbiology and Immunology. He received 1st class honours for his research and was the recipient of the inaugural Stillbirth Foundation Australia PhD Scholarship and Australian Postgraduate Award.His PhD project investigated human cytomegalovirus (CMV) immunomodulation within the placenta during pregnancy and the implications for adverse pregnancy outcomes, in addition to the development of novel antiviral siRNA molecules as a potential therapeutic. During his PhD he accumulated extensive national and international experience and expertise in the fields of virology, immunology, placentology, molecular biology and diagnostics at various leading institutions including the Institute for Clinical and Molecular Biology, University of Nuremberg-Erlangen, Germany.
His research interests include determining the mechanisms by which CMV placental infection can lead to adverse pregnancy outcomes and investigating antiviral compounds for use during pregnancy. Dr Hamilton also has extensive experience as an on-call scientist for the NSW Organ and Tissue Service (DonateLife) where he urgently screens organ and tissue donors for any complicating or life threatening viral infections immediately prior to transplantation.
– Examining the adverse effects CMV infection has on placental development/function and pregnancy outcomes
– Understanding transmission modes of intrauterine CMV infection
– Developing novel ex vivo placental explant histoculture systems for pathogenesis and therapeutic studies
– Investigating CMV antiviral safety and efficacy profiles in human placental models
Project: Experimental and novel CMV antiviral compounds for therapeutic use during pregnancy
Despite the enormous clinical and social importance of congenital CMV, there are currently no licensed therapeutics available for CMV infection during pregnancy. In collaboration with international partners, this project is investigating the safety and efficacy profiles of experimental and novel CMV antiviral compounds in ex vivo human placental models. These investigations are not possible in vivo or in animal models due to potential drug toxicities and the high host specificity of both CMV and placental physiology. Therefore, this project utilises ex vivo placental tissue obtained from women at the Royal Hospital for Women who kindly donate their placenta for this research. This allows vigorous investigations of the effects CMV infection has on human placental development and function and provides a unique model system to investigate a wide range of antiviral therapies for the prevention of intrauterine CMV infection and fetal injury.
