Two Yale professors have resigned after protests condemning the wife's comments that students should be free to push boundaries with Halloween costumes.
Faculty member Erika Christakis, who taught courses on child development and psychology, chose not to keep teaching in the spring semester, the Ivy League university announced via its website on Monday.
It said: 'Her teaching is highly valued and she is welcome to resume teaching anytime at Yale, where freedom of expression and academic inquiry are the paramount principle and practice.'
Mrs Christakis' husband, social and natural sciences professor Nichlas Christakis,has also said he would not teach classes in the spring and would be taking a sabbatical. 'I have great respect and affection for my students, but I worry that the current climate at Yale is not, in my view, conducive to the civil dialogue and open inquiry required to solve our urgent societal problems,' Mrs Christakis said in an email to The Washington Post.
Mrs Christakis came under attack in October for her response to a request from the Intercultural Affairs Committee that students avoid wearing racially insensitive costumes, such as Native American headgear, turbans or blackface.
She wrote in an email to students living in the residence hall where she was an administrator that they should be able to wear any costume they wanted.
'Is there no room anymore for a child or young person to be a little bit obnoxious, a little bit inappropriate or provocative or, yes, offensive?' she wrote.
'American universities were once a safe space not only for maturation but also for a certain regressive, or even transgressive, experience; increasingly, it seems, they have become places of censure and prohibition.'
In a widely shared web video, a student screamed at Mr Christakis after he said he would not stop people from wearing Halloween costumes that could be seen as offensive
The email was one of several incidents on campus that prompted hundreds of students and faculty members to march in protest on November 9 of what they saw as racial insensitivity at the school.
The school also has been dealing with criticism over a residential hall named after John Calhoun, a prominent slave-owning politician, questions about how minorities are treated on campus and allegations that a woman was turned away from a fraternity party because she was not white.
After the march, dozens of faculty members contributed to an open letter showing support for Christakis.
During the 'March of Resilience,' students held signs, including one that read, 'Don't Look Away.'
They chanted, 'We out here. We've been here. We ain't leaving. We are loved' as they marched from the Afro-American Cultural Center across campus and past the Sigma Alpha Epsilon house.
University President Peter Salovey held a four-hour forum with students to hear their grievances and then sent a campus-wide email saying he was deeply troubled by the atmosphere on campus.
He called on the community to come together to create greater 'inclusion, healing, mutual respect and understanding' at Yale.
