The question setters are: Barry Marshall at the University of Western Australia, winner of the Nobel prize in physiology or medicine in 2005 for discovering the role of Helicobacter pylori bacteria in gastritis and peptic ulcer disease. Jennifer Doudna, founder of the Innovative Genomics Institute in Berkeley, California, who won the Nobel prize in chemistry in 2020 for the development of CRISPR gene editing.
