Professor Ruth Hall is in the School of Molecular Bioscience at the University of Sydney, Sydney, Australia. Work in her laboratory focuses on the molecular genetics and genomics of antibiotic resistance in Gram negative bacteria (Escherichia coli, Salmonella enterica, Klebsiella pneumoniae, Acinetobacter baumannii) with particular interests in the identification, characterization and evolution of regions carrying resistance genes, and the molecular mechanisms that lead to the dissemination of the resistance genes. This involves interests in plasmids, genomic islands and transposons as the vehicles that move resistance genes around.
