Summary
John Carreyrou is an American investigative reporter known for his work at The New York Times and previously The Wall Street Journal, where he spent 20 years. Based in various cities including Brussels, Paris, and New York City, Carreyrou is a two-time Pulitzer Prize winner. He gained significant recognition for his series of articles in The Wall Street Journal that exposed the fraudulent practices of the blood-testing company Theranos. Billy Evans, the husband of former Theranos CEO Elizabeth Holmes, has pushed back against the media narrative shaped by Carreyrou's reporting and his book "Bad Blood," arguing that Holmes was unable to publicly defend herself due to a judicial gag order. Evans also clarified his own professional endeavors, distinguishing his new deep-tech startup, Hemanthes, from Theranos and traditional diagnostic labs.
