Defamation Verdict and Immediate Impact
A Suffolk County jury awarded former MIT professor David Sabatini $6 million in damages after finding his former colleague Kristin Knouse defamed him. The jury also dismissed Knouse’s counterclaims of retaliation and harassment. Sabatini, who led a Whitehead Institute laboratory for roughly 24 years, said the decision was “overwhelming” and allowed him to focus on rebuilding his career and family life.
Background & Context
In 2021 an internal Whitehead investigation concluded that Sabatini’s past sexual relationship with Knouse—a former graduate-student mentee—violated the institute’s workplace-relationship policy. Sabatini resigned after the institute received a report from law firm Hinckley, Allen & Snyder LLP on August 13, 2021, received a copy on August 19, and stepped down on August 20 when termination appeared imminent.
Knouse alleged the relationship was coerced; Sabatini maintained it was consensual and that Knouse sought to damage his reputation after he began dating another woman. Sabatini sued Knouse for defamation; the Whitehead Institute was later dropped from the case, leaving Sabatini and Knouse as the sole litigants.
