'''Robin Warren''' (born 11 June 1937) is an Australian [[pathologist]] renowned for his co-discovery, with [[Barry Marshall]], of the bacterium ''[[Helicobacter pylori]]'' and its role in [[gastritis]] and [[peptic ulcer]] disease. This discovery has changed the understanding of the [[stomach]] diseases and led to a paradigm shift in their treatment, moving away from surgeries and towards antibiotic therapies. For their work, Warren and Marshall were awarded the [[Nobel Prize in Physiology or Medicine]] in 2005.

==Early Life and Education==
Robin Warren was born in [[Adelaide]], [[South Australia]]. He attended the University of Adelaide, where he earned his degree in medicine in 1961. After completing his medical degree, Warren embarked on a career in pathology with a focus on pathology of the stomach.

==Career and Discovery==
Warren spent the majority of his career at the Royal Perth Hospital in [[Perth]], Western Australia, where he worked as a clinical pathologist. It was here, in 1979, that Warren first observed small, curved bacteria in the lower part of the [[stomach]] in about 50% of patients from which biopsies had been taken. This observation was initially met with skepticism, as the stomach was believed to be too acidic to harbor bacteria.

Despite the initial disbelief, Warren continued his research into these bacteria, which would later be named ''Helicobacter pylori''. His collaboration with Barry Marshall, a young clinical fellow, was pivotal. Together, they conducted a study that demonstrated the presence of ''H. pylori'' in almost all patients with chronic [[gastritis]], [[duodenal ulcer]], and [[gastric ulcer]]. This was contrary to the prevailing belief that stress and lifestyle were the primary causes of these conditions.

Their findings were initially met with resistance from the medical community. However, the duo persisted with their research, and by the late 1980s and early 1990s, the link between ''H. pylori'' and stomach ulcers was increasingly accepted. This led to a significant change in the treatment of [[peptic ulcer disease]], with antibiotics to eradicate ''H. pylori'' becoming the standard of care, dramatically reducing the need for surgery to treat the condition.

==Nobel Prize==
In 2005, Robin Warren and Barry Marshall were jointly awarded the Nobel Prize in Physiology or Medicine "for their discovery of the bacterium ''Helicobacter pylori'' and its role in gastritis and peptic ulcer disease." This accolade was a testament to their significant contribution to medical science, particularly in the field of gastroenterology.

==Legacy==
Warren's work has had a profound impact on the understanding and treatment of stomach diseases. His discovery has not only led to more effective treatments for [[peptic ulcer disease]] but has also spurred further research into the role of ''H. pylori'' in other conditions, such as [[stomach cancer]] and [[MALT lymphoma]].

==Personal Life==
Outside of his professional achievements, Warren is known to have a keen interest in photography, particularly in natural and microscopic subjects. He is married and has children.
