Harvard University fired a professor accused of falsifying data related to her research on ethical behavior, the first time the Ivy League institution has dismissed a tenured instructor since rules for academic protections were formalized.

The historic decision to revoke Francesca Gino’s tenure follows a Harvard investigation into allegations she falsified data used in research papers focused on dishonesty. The university’s investigation concluded last year that the Harvard Business School professor “engaged in multiple instances of research misconduct” in four separate research papers.
