But a 113-page dossier obtained by Science from a small group of whistleblowers paints a less encouraging picture …
The dossier highlights evidence that dozens of papers from Zlokovic’s lab—including many supporting the idea that the compound was ready for human testing—contain seemingly doctored data that suggest scientific misconduct …
Speaking to Science anonymously, four former members of Zlokovic’s lab say the anomalies the whistleblowers found are no accident. They describe a culture of intimidation, in which he regularly pushed them and others in the lab to adjust data. Two of them said he sometimes had people change lab notebooks after experiments were completed to ensure they only contained the desired results. “There were clear examples of him instructing people to manipulate data to fit the hypothesis,” one of the lab members says.
