Barry Marshall

Winner of the 2005 Nobel Prize in the Physiology or Medicine category for his discovery of the role of the bacterium helicobacter pylori in peptic ulcers, Marshall discusses his early years, his passion for electronics, his family and the path that led him to success in science. He also talks about the many hurdles he had to overcome, including the skepticism of the scientific community when he decided to play “guinea pig” and use the results of his research to conduct experiments on himself. Now that microbiota is in the spotlight, further scientific advances are imminent in the field of gastroenterology.
