Research in Steve Busby’s lab is concerned with understanding the molecular mechanisms that control gene expression in bacteria, with particular attention to studying the regulation of transcription initiation in Escherichia coli. Much of the recent work has focussed on the expression of virulence determinants in pathogenic strains.


  • BA 1972 University of Cambridge, Natural Sciences 
  • DPhil 1975 University of Oxford


Steve teaches on undergraduate courses at all levels. His biggest contributions are to a second year course on bacterial genes and genomes, and a third year course on bacterial gene regulation. He is currently the Coordinator for the School’s Taught Masters and MRes Programmes.
