A Suffolk County Superior Court jury in Boston found on Oct. 16 that biologist Kristin Knouse defamed David Sabatini, the former MIT professor and Whitehead Institute lab head whose career collapsed after she accused him of sexual misconduct in 2021. The jury awarded Sabatini $6 million plus interest and found that Knouse interfered with his ability to make a living, STAT reported. It rejected her counterclaims of sexual harassment, a sexualized hostile work environment and retaliation, according to Boston 25 News.

The jury of seven women and six men reached its verdict after a three-week trial. Knouse’s lawyer, Ellen Zucker, said her client will appeal.

How the case began

Sabatini, 58, ran a lab at the Whitehead Institute in Cambridge for 24 years, Boston.com reported, citing the New York Times. The Whitehead is an independent nonprofit affiliated with MIT, where Sabatini also held a professorship.

According to the Boston Globe, the two met at a conference in Washington, D.C., in 2018 and had sex in his hotel room that night. Both agree on that much. Sabatini says it was consensual. Knouse says she resisted and was coerced. The secret relationship lasted about a year and a half and ended in January 2020, when Sabatini told her he wanted to pursue another scientist, the Globe reported.

In 2021 the Whitehead hired outside investigators after complaints, including one from Knouse. They found the relationship violated Whitehead policy and that Sabatini “engaged in and otherwise tolerated sexist and sexualized work discussions” in his lab, the Globe reported. He resigned in August 2021. MIT suspended him and the Howard Hughes Medical Institute fired him, The Scientist reported. Then-MIT President L. Rafael Reif said Sabatini had “behaved in ways incompatible with the responsibilities of faculty membership.”

What the jury heard

Documents shown at trial included Knouse’s own name for her effort against Sabatini: “Covert Operation Dethrone,” Boston 25 News reported. In one message she joked about buying a “Lambo” if she won a settlement. In an April 15, 2021 exchange she wrote, “He should have none.”

Knouse admitted she chose which text messages to give the investigators and did not hand at least one exchange to the law firm Hinckley Allen. “I was trying to make my own judgments about what was relevant,” she said, according to Boston 25. Online summaries of the case have described the texts as “manipulated.” No report we reviewed supports that word. What is on the record is selective production, which Knouse acknowledged.

Sabatini’s lawyer, Lisa Arrowood, did not defend the affair itself. “The biggest mistake of his life. But was it rape? Absolutely not,” she told jurors, the Globe reported. Zucker’s answer was shorter: “There were rules. He broke them.”

Who held the power

The power question is central, and the record does not cut one way. Sabatini was the senior figure. The Globe describes Knouse as “a much younger colleague whose career he was in a position to influence.” He had been her teacher and mentor, and in 2018 she was about to start as a Whitehead Fellow, a program that funds young scientists to open their own labs. In August 2018, while the affair was under way, the Whitehead banned faculty and lab heads from sexual relationships with any Whitehead employee. Sabatini’s own lawyer called the affair a mistake.

The jury, though, heard that power imbalance and still found that Knouse defamed him, rejecting her claims of harassment and retaliation. Which specific statements the jury found false has not been detailed in the coverage we reviewed. The verdict also does not reverse the Whitehead’s finding that he broke its relationship rules. It does mean a jury found that the accusations that cost him his lab crossed into defamation.

Loose ends

Sabatini’s original suit also named the Whitehead Institute and its director, Ruth Lehmann, for defamation and gender discrimination. Earlier judges dismissed those claims, and Judge Christopher Barry-Smith called the remaining defamation case “thin” when he let it go to trial, The Scientist reported. MIT says the Whitehead is an independent nonprofit, the Globe reported, and the Whitehead was not a party at trial after the claims against it were dismissed. Knouse is now an MIT assistant professor of biology and a faculty member of its Koch Institute.

Sabatini rebuilt his career outside the old system. New York University did not hire him after protests in 2022, and Prague’s Institute of Organic Chemistry and Biochemistry hired him in 2023, Boston.com reported. Investor Bill Ackman pledged $25 million over five years to his new lab, alongside an anonymous donor, and Sabatini has since opened a second lab in Boston, according to the Globe. “It’s surreal,” he said after the verdict.

The case has already become a political argument. In a Fox News opinion column, Mike Davis of the Article III Project wrote that “The Trump administration must investigate MIT and Whitehead.” That is a call for action, not a finding of the court. Zucker framed the verdict the other way, saying “society still has a difficult time believing women.”

What can be checked next: post-trial motions, the appeal Zucker promised, and whether the Whitehead or MIT revisit how the 2021 investigation was run.
