Dr. Barry J. Marshall was awarded the 2005 Nobel Prize in Physiology/Medicine for the discovery of Helicobacter pylori as well as its role in peptic ulcers. His work overturned the canonical wisdom that bacteria cannot survive in the stomach as well as establishing a definitive, microbiological treatment for ulcers – estimated to have saved over a million lives.
Currently Dr. Marshall is a Clinical Professor at the University of Western Australia, where he leads the Marshall Centre for Infectious Diseases Research and Training (founded in his honour). Dr. Marshall further serves as a Consultant Gastroenterologist at the Sir Charles Gairdner Hospital. His present research interests expand on his ground-breaking work and is seeking novel strategies to manage immunity via the microbiome as well as devise early diagnostic methods for bowel syndromes.
