On October 14, 2026, a Suffolk County jury in Boston awarded former MIT biologist Dr. David Sabatini $6 million in damages after finding that his former colleague, Dr. Kristin Knouse, defamed him by alleging sexual misconduct.
What happened
Dr. Sabatini, who led a research lab at the Whitehead Institute for Biomedical Research in Cambridge, Massachusetts for roughly 24 years, was dismissed from the institute in 2021 following an internal investigation into allegations made by Dr. Knouse. The two scientists met in 2012, began a consensual sexual relationship in 2018, and ended it in 2019, according to court documents obtained by Fox News Digital. Knouse later claimed the relationship was coerced and filed a sexual‑harassment complaint in 2021.
What the report adds
The New York Post article notes that the internal Whitehead investigation concluded Sabatini had fostered a "sexualized atmosphere" in his lab, prompting his resignation. Sabatini subsequently sued Knouse for defamation, tortious interference and related claims, while Knouse filed a counter‑claim alleging sexual harassment. During the trial, Sabatini’s attorney, Lisa Arrowood, presented text messages from 2020 showing Knouse expressing willingness to continue the relationship and later indicating jealousy over another woman Sabatini was interested in.
What was said
After the verdict, Sabatini told Fox News Digital that the decision was “overwhelming.” The article also quotes a 2020 message from Knouse in which she wrote, “pouring a lot of energy and emotion into a game I’m destined to lose,” and later added, “But most times I feel at peace and want to do everything and anything I can to help you.”
How it came about
Sabatini’s departure from Whitehead occurred amid a broader investigation at MIT into his conduct. The defamation suit was filed after the internal probe, and the jury’s $6 million award marks the latest development in a dispute that began with the 2021 harassment allegation.
