Former MIT Scientist and Accuser Prepare Appeals After $6 Million Defamation Verdict

A Massachusetts jury has awarded former MIT biologist David Sabatini $6 million in his defamation lawsuit against former colleague Kristin Knouse. Knouse is appealing the October verdict, and Sabatini’s legal team plans to challenge a separate ruling that dismissed the Whitehead Institute from the case.

Knouse’s attorney, Ellen Zucker, argues that the verdict could discourage women scientists from reporting misconduct. She said the prospect of being sued may make people reluctant to take part in workplace investigations.

Sabatini’s attorney, Lisa G. Arrowood, countered that the verdict should not affect people who report harassment or abuse truthfully. She said the jury concluded that Knouse’s allegations were false and defamatory, based in part on documents written at the time by Knouse herself.

Arrowood said she expects Knouse’s appeal to fail, noting that the trial judge had often ruled in Knouse’s favor on close questions. Zucker, meanwhile, said her client told the truth about her experiences and that other women also spoke to investigators, who found violations of institutional policy.

The dispute dates back to 2012, when Knouse was a doctoral student in the Harvard-MIT M.D./Ph.D. program and Sabatini sat on her thesis committee. They began a relationship in 2018, after Knouse became a Whitehead Fellow, according to court documents.

Sabatini has described the relationship as consensual. Knouse said it was coerced and created an inappropriate workplace dynamic. A Whitehead Institute investigation in 2021 found that Sabatini had violated the institute’s policy on workplace relationships.

Messages presented during the case included Knouse writing that she worried she was being treated as a backup and was competing with other women. In another message, referring to a visit to Sabatini’s hotel room during a work retreat, she later described his behavior as aggressive. Messages also showed Knouse referring to a campaign against Sabatini as “Covert Operation Dethrone” and joking about buying a Lamborghini if she received a settlement.

Arrowood said Sabatini’s case was not an attack on the MeToo movement or women’s right to report harassment. Rather, she said, the jury found that Knouse had fabricated claims to harm him.

After Knouse made her allegations, MIT removed Sabatini from his tenured position, the Howard Hughes Medical Institute dismissed him, and the Whitehead Institute ousted him. MIT and the medical institute were not defendants in the defamation case.

MIT declined to comment on the lawsuit, referring to a 2022 letter stating that Sabatini had behaved in ways incompatible with faculty responsibilities. The Howard Hughes Medical Institute did not respond to a request for comment.

The institutions relied on internal Title IX investigations, which found that Sabatini had violated their policies by having an undisclosed romantic relationship with a junior researcher. Such campus proceedings generally use a lower standard of proof and may not allow the accused to cross-examine the person making the allegation.

Arrowood argued that the institutions acted before the evidence had been fully tested. She said investigators and the Whitehead Institute allowed one side to control what evidence they reviewed and what was shown to Sabatini. In her view, a fuller record might have changed the institutions’ decisions.

At trial in Suffolk County, jurors rejected Knouse’s counterclaims and ordered her to pay Sabatini millions of dollars in damages for defamation. Sabatini’s legal team is also seeking to overturn the earlier dismissal of the Whitehead Institute from the lawsuit.

The case has taken a substantial toll on Sabatini’s U.S. research career. Billionaire investor Bill Ackman helped fund a new laboratory for him in Prague, where he continues cancer research. Sabatini has said the ordeal left him feeling that he had lost his normal life and that he worried about whether he could endure it financially, emotionally, or physically.

The case will now move to the Massachusetts appellate courts. A briefing schedule has not yet been set.
