Robin Warren

Robin Warren is an Australian pathologist best known for his research on the role of bacteria in stomach ulcers and gastric cancer. In the 1970s, he and his colleague Barry Marshall discovered that the bacterium Helicobacter pylori can cause these conditions, which challenged the prevailing belief that stress and lifestyle were the main causes. Their groundbreaking work led to new treatments for ulcers and improved understanding of stomach diseases, significantly impacting medicine. In 2005, Warren and Marshall were awarded the Nobel Prize in Physiology or Medicine for their discoveries, highlighting the importance of microbial infections in digestive health.
