Ivy prof is accused of sex harass

A LONGTIME Columbia University professor sexually harassed a student and then badmouthed her because she spurned his lecherous advances, a new lawsuit alleges.

The suit, filed Monday by an anonymous doctoral student, alleges the 79-year-old scholar, William Harris, routinely made passes at her.

Harris, who specializes in Greek and Roman history, angled on getting the 29-year-old student into bed from 2014 to 2015, the Manhattan Federal Court suit claims. As a result, the woman had to withdraw from the 2015-2016 school year to get counseling, she charges.

Harris — who has taught at the school for more than 50 years — understood his actions “violated sexual harassment policies and (were) beyond all possible bounds of decency.”

Throughout his time at the university, the big-shot academic “has harassed female assistants, students and fellow faculty members,” the lawsuit insisted.

What’s worse, the suit said, the school knew of Harris’ behavior but was “deliberately indifferent.”

Harris told The News he had no comment on the allegations.

In a statement, Columbia said, “We treat any claim of harassment or other gender-based misconduct in our community with the utmost seriousness.”
