Rate My Professor Tracy Palmer

Palmer's research specializes in bacterial protein secretion systems, focusing on the Type VII secretion pathway (T7SS) in Gram-positive bacteria such as Staphylococcus aureus and Mycobacterium abscessus. Her group has identified key substrates like the nuclease EsaD, toxins TspA and TslA, and elucidated mechanisms of interbacterial competition and phage defense. She co-discovered the Twin-Arginine Translocation (Tat) system for folded protein export. Notable contributions include development of E. coli strains for molybdenum cofactor studies. Key publications encompass 'Multiple variants of the type VII secretion system in Gram-positive bacteria' (microLife, 2024), 'A type VII-secreted lipase toxin with reverse domain arrangement' (Nature Communications, 2023), 'High-throughput functional analysis provides novel insight into type VII secretion in Staphylococcus aureus' (Open Biology, 2024), and 'Distinct immunity protein families mediate compartment-specific neutralization of a bacterial toxin' (Cell Reports, 2025). Her accolades include Fellow of the Royal Society (FRS, 2018), Academy of Medical Sciences (FMedSci, 2021), Royal Society of Edinburgh (FRSE, 2009), EMBO membership (2017), American Academy of Microbiology fellowship (2015), and Microbiology Society Fleming Medal (2002). Her discoveries have profoundly influenced understanding of bacterial antagonism and secretion machineries.
