Scientist Wins $6 Million After Jury Finds Colleague Lied About Sexual Misconduct Allegations

Renowned molecular biologist David Sabatini has been awarded $6 million after a jury determined that his former colleague, Kristin Knouse, made false accusations of sexual misconduct against him. The jury in Suffolk Superior Court found Knouse liable for defamation and interference with Sabatini's ability to earn a living.

Sabatini, 58, was ousted from his prestigious positions at the Whitehead Institute and the Massachusetts Institute of Technology (MIT) in 2021 following allegations of an inappropriate and abusive affair with Knouse, then 38. The accusations surfaced amid the #MeToo movement, with Knouse and other researchers alleging Sabatini ran a toxic and sexually charged laboratory.

Sabatini filed a civil lawsuit five years ago, asserting he was the victim of a smear campaign initiated by Knouse after he ended their relationship. Knouse subsequently countersued, alleging Sabatini abused his power to coerce her into an unwanted relationship and work environment.

The three-week civil trial concluded with the jury ruling in favor of Sabatini. His legal team argued that the allegations had destroyed his reputation, costing him nearly $2 million in lost earnings between 2020 and 2025. Sabatini testified that the downfall led to depression and an attempted suicide.

The relationship between Sabatini and Knouse began in 2018 at a conference in Washington D.C., where Sabatini was mentoring Knouse as she prepared to start her own laboratory. Both acknowledged having consensual sexual relations at the conference, though Knouse later stated she felt coerced. Evidence presented by Sabatini's attorneys included text messages from Knouse the following morning expressing no regret.

Their affair continued for approximately 18 months, during which they reported having sex about 15 times while maintaining a professional relationship. Sabatini stated that while he continued to mentor Knouse, their relationship shifted when she sought greater commitment in 2019. Knouse's legal team contended that she felt pressured due to Sabatini's professional standing and felt exploited.

Their relationship ended in January 2020 when Sabatini informed Knouse he wished to date another scientist. Shortly after, Knouse reported Sabatini to the Whitehead Institute for alleged misconduct. An internal investigation by the institute concluded that Sabatini fostered "sexist and sexualized work discussions," leading to his resignation in August 2021. He also resigned from his tenured position at MIT the following year.

Sabatini's attorneys stated the jury rejected Knouse's case entirely, finding she defamed Sabatini and interfered with his professional relationships. "We are so happy that we got David Sabatini's good name back," Sabatini's attorney, Lisa Arrowood, told The Boston Globe. "Now he can be regarded as the brilliant scientist he is."

Sabatini expressed to The New York Times his hope that the verdict signifies a step toward regaining his reputation, stating he wants to be judged again by his scientific work and mentorship.

Knouse's attorney, Ellen Zucker, indicated that her client plans to appeal the verdict. Zucker stated that Knouse and her team "engaged in this particular legal battle" because they believed it was the right course of action and intend to continue their fight. Zucker added that multiple women testified about Sabatini's conduct and that the verdict is "unfortunate" for them and for a culture that struggles to hold men accountable and believe women.
