John Carreyrou, a two-time Pulitzer Prize winner, was a reporter at The Wall Street Journal for twenty years.

Bad Blood, a fearlessly written and gripping story about Theranos founder and CEO Elizabeth Holmes, was named the Financial Times and McKinsey Business Book of the Year.

For his extensive coverage of Theranos, Carreyrou was awarded the George Polk Award for Financial Reporting, the Gerald Loeb Award for Distinguished Business and Financial Journalism in the category of beat reporting, and the Barlett & Steele Silver Award for Investigative Business Journalism.
