John Carreyrou

John Carreyrou is a French-American investigative journalist best known for exposing the fraudulent practices of blood-testing company Theranos and its founder Elizabeth Holmes. His investigative work for The Wall Street Journal led to the company's downfall and resulted in his bestselling book "Bad Blood: Secrets and Lies in a Silicon Valley Startup" (2018). During his two-decade career at The Wall Street Journal (1999-2019), Carreyrou earned two Pulitzer Prizes for his investigative reporting. His coverage spanned multiple beats and locations, including roles as bureau chief for health and science in New York and deputy bureau chief for Southern Europe, based in Paris. Born to a French journalist father and American mother, Carreyrou grew up in Paris and graduated from Duke University with a degree in political science. His journalism career began at Dow Jones Newswires before joining The Wall Street Journal Europe in Brussels, where he established himself as a skilled investigative reporter. Carreyrou's most significant impact came through his 2015 investigation into Theranos, which revealed the company's deceptive practices and technological limitations. Despite pressure from Theranos and its powerful allies to suppress the story, his reporting ultimately led to criminal charges against Elizabeth Holmes and the company's collapse.
