Professor Barry Marshall

Barry Marshall is known around the world for his discoveries about the cause of peptic ulcers. His bold self-experimentation led to a complete change in the treatment of the condition world-wide. In 2005 he was awarded the Nobel Prize for Medicine for this work, shared with Robin Warren.

Professor Marshall (Senior Principal Research Fellow, School of Biomedical, Biomolecular and Chemical Sciences) completed his undergraduate medical degree at UWA in 1974. He met Robin Warren, a pathologist interested in gastritis, during internal medicine fellowship training at Royal Perth Hospital in 1981. Together, the pair studied the presence of spiral bacteria in association with gastritis. The following year (1982), they performed the initial culture of Helicobacter pylori and developed their hypothesis related to the bacterial cause of peptic ulcer and gastric cancer.

In 1984, while at Fremantle Hospital, Professor Marshall fulfilled Koch's postulates for H. pylori and gastritis in a well-publicised self-administration experiment, in which he drank a culture of H. pylori. Following that, he did research at the University of Virginia, USA, before returning to Australia in 1997. He held a Burnet Fellowship at the University of Western Australia from 1998-2003.

Professor Marshall continues research related to H. pylori and runs a molecular biology lab at UWA. More details on Professor Marshall can be found at the Academy of Achievement.
