What makes John Carreyrou a Global Shaker?

John Carreyrou is an investigative journalist based at the Wall Street Journal who has won two Pulitzer Prizes in 2003 and 2015. He grew up in France where his father, Gerard Carreyrou, was a journalist. His mother is from the US. Carreyrou graduated from Duke University in 1994 with a bachelors in political science and government. He now resides in Brooklyn with his wife and two children.

Upon his graduation, he worked at Dow Jones Newswires before joining the Wall Street Journal Europe in Brussels in 1999. After two years with the paper, he was moved from Belgium to Paris in order to cover French Business. After four years with the Journal, he became the deputy bureau chief for Southern Europe where his writing continued to focus on French business as well as politics and news in Spain and Portugal. He then moved to New York where he has had the positions of deputy bureau chief and bureau chief of Health and Science.

Carreyrou is perhaps best known for his work on the project, “Medicare Unmasked”.  His research on Medicare, along with the work of a team of investigative journalists, forced the US government into releasing important Medicare data that has been withheld from the public for decades. The series also ascertained activities within the government that cost taxpayers billions.  In May 2018 Carreyrou released  Bad Blood: Secrets and Lies in a Silicon Valley Startup.
