Tracy Palmer is Professor of Microbiology at Newcastle University, UK. She is a molecular microbiologist who has made leading contributions to the understanding of bacterial protein secretion systems. She is a co-discoverer of the bacterial twin-arginine protein translocation (Tat) pathway, a system that transports folded proteins, across the cytoplasmic membrane of bacteria. She also works on the Type VII secretion system in the human pathogen Staphylococcus aureus, revealing an unexpected and critical role for this pathway in interbacterial competition, with important implications for shaping the microbiota. Follow-up studies have confirmed it to be a widespread feature of this secretion system among Gram-positive bacteria. Tracy has received numerous accolades for her work including election to Fellowship of both the Royal Society of London and the Royal Society of Edinburgh, and to Membership of the European Molecular Biology Organisation.
