An assistant professor in Columbia University’s business school has filed a sexual harassment suit against the school, alleging that a senior professor sabotaged her work after she rejected his sexual advances and that Columbia refused to take steps to curb his behavior.

Enrichetta Ravina, an assistant finance professor, alleges in Ravina v. Columbia University, 16-cv-2137, that business professor Geert Bekaert used his authority to stall her research after she rebuffed him. Bekaert is not a party in the lawsuit.
