Julie O’Sullivan is a postdoctoral researcher with APC Microbiome Ireland at University College Cork in the research group Microbes to Molecules. She recently completed her Ph. D, also with the APC, in Moorepark Food Research Centre, Fermoy, Co. Cork under Prof. Paul Ross, Dr. Mary Rea and Prof. Colin Hill. Her Ph. D research has focused on mining the human skin microbiota for much needed alternatives to antibiotics, primarily antimicrobial peptides called bacteriocins, that exhibit health potential against a wide range of pathogens, including skin pathogens. She is now continuing her research in this area to further explore the gut- skin connection.
