Jury Orders Biologist's Accuser to Pay $6 Million in Closely Watched Lab Dispute

A Massachusetts jury has ordered scientist Kristin Knouse to pay $6 million, plus interest, to biologist David Sabatini, finding that she defamed him and interfered with his professional relationships. The verdict came Oct. 16, 2026, in Suffolk County Superior Court. Knouse's lawyer says she will appeal, so the five-year dispute is not over.

Sabatini, a prominent cell-growth researcher, lost his post at the Whitehead Institute for Biomedical Research after a workplace investigation. Knouse says he pressured her into a relationship. He says it was consensual. The two sides offer sharply different accounts.

What the jury decided

According to Law Commentary, jurors found that Knouse defamed Sabatini by describing him as a sexual predator. The same jury rejected her counterclaims of sexual harassment and retaliation. The Boston Globe, as cited by SuaraGarut.ID, reported that the jury was unanimous after a three-week trial in which former lab members gave conflicting accounts. Some described a toxic, sexually charged workplace, while others praised his mentorship and leadership.

Sabatini's side

Sabatini says the relationship, which began in 2018, was consensual. According to University Herald, he argued that the accusations followed the end of the relationship and that Knouse tried to get him fired and damage his reputation. He sued on Oct. 20, 2021, according to Law Commentary. He says the allegations kept him from securing another academic position.

His attorney, Lisa Arrowood, welcomed the verdict and said it restored his reputation. Sabatini told The Boston Globe he was still absorbing the outcome: “I don't know if I still believe it, to be honest with you.”

SuaraGarut.ID reported that he has since resumed research with financial backing that included a $25 million commitment over five years from investor Bill Ackman and an anonymous donor. Ackman has publicly defended him and urged MIT to say whether it would reinstate his tenure.

Knouse's side

Knouse, a former mentee of Sabatini who is now an assistant professor of biology at MIT, says he used his authority to pressure her into the relationship. She also says he fostered a hostile, sexualized workplace. According to Law Commentary, she said the power imbalance made it hard to end the relationship.

Her lawyer, Ellen Zucker, said Knouse told the truth. Zucker also pointed to testimony from other women about conditions in the lab and called it disappointing that the jury did not credit it. Knouse declined to comment after the verdict, according to The Boston Globe.

What the institutions say

The Whitehead Institute said all claims against it were dismissed earlier, so it was not a party to the trial. It stressed that the judgment applies only to Sabatini and Knouse. Its earlier finding that Sabatini violated workplace policies remains unchanged, according to Law Commentary.

MIT said the Whitehead Institute is an independent nonprofit and that the university was not a party to Sabatini's original lawsuit, according to a statement from spokesperson Kimberly Allen, cited by SuaraGarut.ID. Reports differ on when Sabatini left Whitehead. University Herald and Law Commentary say 2021, while SuaraGarut.ID says 2022.

What this means beyond the courtroom

The verdict resolves the claims between two individuals, not the question of how institutions handled the case. For people working in university labs, the more lasting legal point may come from an earlier ruling. On May 19, 2026, Massachusetts' Supreme Judicial Court revived Knouse's harassment counterclaim, according to Law Commentary. It held that state law lets people alleging harassment in academic settings sue the accused individuals directly. That ruling addressed who can be held liable, not whether Knouse's allegations were true, and the jury later ruled against her on those claims.

Sabatini has called for more transparency and accountability in how academic institutions investigate allegations and make employment decisions, SuaraGarut.ID reported. Former Harvard Medical School dean Jeffrey Flier has raised due-process concerns about the investigation and questioned what the verdict means for MIT's response.

What happens next

Zucker said Knouse intends to appeal, which could send the case back to Massachusetts appellate courts. How the $6 million award, plus interest, will affect Knouse financially remains unclear while she prepares that appeal, according to SuaraGarut.ID.
