The Ramsay lab was established in 2013 and is based in the Curtin Health Innovation Research Institute and School of Pharmacy and Biomedical Sciences, Curtin University, Western Australia.
Mobile genetic elements such as plasmids, bacteriophage and chromosomally-integrating elements are ubiquitous in bacteria and drive evolution through horizontal gene transfer.
We investigate the gene regulation, evolution and molecular biology of bacterial mobile genetic elements - along with a plethora of other interesting things we get our hands on!
The Ramsay lab currently studies mobile genetic elements active in both human pathogens (Staphylococcus aureus) and beneficial nitrogen-fixing plant-associated rhizobia (Mesorhizobium spp).
