Former Massachusetts Institute of Technology scientist David Sabatini has been awarded $6 million by a Boston jury after it found that former colleague Kristin Knouse defamed him and improperly interfered with his professional relationships. Knouse’s lawyers say she intends to appeal.
The decision, delivered on 16 October 2026 following a three-week civil trial in Suffolk County Superior Court, is a major development in a dispute that began with sexual misconduct allegations and workplace investigations five years earlier. The jury also rejected Knouse’s counterclaims of sexual harassment and retaliation.
In his first on-camera interview following the verdict, Sabatini told Boston 25 News: “I lost everything. There was nothing left of my normal life.” The scientist said the affair had cost him his laboratory, career prospects and reputation.
What did the jury decide?
Sabatini sued Knouse for defamation and interference with existing and prospective professional relationships. The jury found in his favour on those claims and awarded $6 million in damages, with interest potentially adding to the total.
Knouse had maintained that their sexual relationship was coercive and brought counterclaims alleging harassment and retaliation. The jury rejected those claims. This was a civil trial between the two scientists, not a criminal proceeding.
Sabatini’s legal team said the result vindicated him. In a statement issued on 19 October, law firm Arrowood LLP said the jury had considered messages and other evidence about the relationship, the allegations and their consequences.
Why did Sabatini leave MIT and Whitehead?
Sabatini was a prominent cell biologist whose research concerned the mechanisms regulating cell growth, including work relevant to cancer and other diseases. He led a laboratory at the Whitehead Institute for Biomedical Research, which is affiliated with MIT.
In 2020, concerns about conduct in his laboratory prompted an independent workplace investigation. That investigation concluded he had breached Whitehead policies, including policies concerning sexual harassment, and described a sexualised working environment. Sabatini disputed the misconduct allegations, maintaining that his relationship with Knouse was consensual. He left Whitehead in 2021 and later lost his MIT position.
The Massachusetts Supreme Judicial Court’s earlier May 2026 ruling summarised the workplace investigation and the competing allegations while deciding a legal question about whether a harassment claim could be brought against an individual in an academic setting. That pre-trial ruling did not establish the allegations as proven facts.
What emerged in the new interview?
In the Boston 25 News investigation published on 27 October, reporter Ted Daniel examined text messages and deposition evidence presented during the litigation. The station reported that Knouse acknowledged choosing which messages to give the original investigators and not providing at least one exchange. Her explanation was that she had been making her own judgement about relevance.
The programme also reported on communications suggesting hostility towards Sabatini after their relationship ended. Those communications formed part of the evidence advanced in court; they should not be mistaken for a complete record of the relationship or for findings about every disputed allegation.
What have Knouse and Whitehead said?
Knouse’s lawyer, Ellen Zucker, said her client intended to appeal. Speaking after the verdict, Zucker maintained that Knouse had told the truth and criticised the decision. An intention to appeal is not the same as confirmation that a formal appeal has already been filed.
Whitehead Institute said its board continued to have full confidence in its leadership, workplace policies and the independent 2021 investigation. It also stressed that Whitehead was not a party to this trial and that Sabatini’s claims against the institute had already been dismissed by the court.
That distinction matters. The jury ruled on the claims and counterclaims between Sabatini and Knouse. It did not formally overturn Whitehead’s institutional findings or adjudicate every allegation concerning conduct in the laboratory.
What happens next?
The $6 million award is a significant civil verdict, but the dispute may continue through post-trial proceedings and any appeal. As at 29 October, the reporting reviewed by Fish 4 News establishes an announced intention to appeal, not the outcome of an appeal.
