What is the reputation of John Carreyrou, the investigative reporter who wrote a critical piece about Theranos, like?

John Carreyrou 's Wikipedia page does a good job of summarizing his rather stellar journalism career thus far. Focusing on American journalism awards, during his time at the The Wall Street Journal (WSJ), he's won two Pulitzer Prizes and one Polk Award,

• One, a shared Pulitzer prize for Explanatory Reporting in 2002 for coverage of some corporate scandals (1, 2),
• Two, a shared Pulitzer prize for Investigative Reporting in 2015 for coverage of widespread US medical doctors' bilking of Medicare (see photo below from 3; 4, 5, 6).

• Three, in 2016, the George Polk Awards bestowed Carreyrou an individual Financial Reporting award for his coverage of Theranos. The Polk citation states (7, 8),

'The award for Financial Reporting will go to John Carreyrou of The Wall Street Journal whose investigation of Theranos, Inc. raised serious doubts about claims by the firm and its celebrated 31-year-old founder, Elizabeth Holmes, that its new procedure for drawing and testing blood was a transformational medical breakthrough in wide use at the firm’s labs. Carreyrou’s well-researched stories, reported in the face of threats of lawsuits and efforts to pressure some sources to back off of their accounts, led to a reevaluation of Theranos’ prospects among investors and have been followed by regulatory actions against the company and widespread discussion that publications and institutions from Fortune and The New Yorker to Harvard and the White House may have been too quick to hail Holmes, a Stanford dropout whose personal wealth at the height of her startup’s rise was an estimated $4.5 billion, as a success story in the tradition of Steve Jobs, Bill Gates and Mark Zuckerberg'

Let's also be clear. John Carreyrou didn't write 'a' but rather all the relevant critical WSJ pieces about Theranos either alone (9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20) or with Rolfe Winkler (21) or with Christopher Weaver and/or Michael Siconolfi (22, 23, 24, 25, 26, 27, 28).

In contrast to the 'access-driven cheerleading' (29) currently consuming technology journalism, Carreyrou pursued the Theranos case with dogged determination. Key aspect of the Carreyrou-WSJ Theranos exposes includes the numerous former and present as-yet anonymous employees who apparently proffered sensitive information at considerable peril to themselves. Clearly Carreyrou is skilled in seeking out and cultivating confidential contacts crucial to his story. Kudos to Carreyrou-WSJ for continuing to maintain their contacts’ confidentiality and for not caving to the alleged intimidating legal tactics used by Theranos (see excerpt below from 30).

'After two months of being stonewalled by the Theranos P.R. team, Carreyrou told me an entourage of lawyers arrived at the Journal ’s Midtown Manhattan offices at one P.M. on June 23. The pack confidently sauntered past editors and reporters in the fifth-floor newsroom and was led by David Boies, the superstar lawyer who has taken on Bill Gates, the U.S. government, and represented Al Gore in the 2000 Florida recount case. Four other attorneys and a Theranos representative accompanied him. Before anything was said, the lawyers placed two audio recorders at either end of the long oval wood table, and recalcitrantly sat across from Carreyrou, his editor, and a Journal lawyer. Then they hit record.

Almost immediately, one person present told me, Boies and his team threatened legal action against the paper, accusing it of being in possession of “proprietary information” and “trade secrets.” The Theranos legal team then did their best to discredit dozens of independent sources whom Carreyrou had interviewed. The legal team roared, they showed teeth, they tried to intimidate. After a very tense five hours, the person told me that Boies and his platoon exited the newsroom, leaving behind the very serious specter of a lawsuit. (A spokesperson for both Boies and Theranos declined to comment. But one person close to the company said that Boies had been dispatched because Theranos executives had learned that the Journal possessed sensitive internal documents.)

For four months after that meeting, Carreyrou continued to try to secure an interview with Holmes, and for four months he was continuously threatened. Finally, in October, the Journal published its now-famous article suggesting that the Theranos narrative was all wrong—that the company’s technology was faulty, that it relied on other companies’ machinery to run many of its tests, and that some of those tests yielded inaccurate results. In fact, as Carreyrou reported, the company was hawking a tale that was too good to be true.'
