Barry Marshall is a Professor of Clinical Microbiology at the University of Western Australia. Alongside Robin Warren, he received the Nobel Prize in Physiology or Medicine in 2005 for first showing that Helicobacter pylori bacteria, rather than acid, were the cause of stomach ulcers. For this, Marshall did a self-experiment where he ingested H.pylori and gave himself acute gastritis, establishing a first link between the infectious agent and the development of gastric disorders.
