Cornell University President Martha Pollack announced she will retire on June 30 in a Thursday email sent to the campus community.

Pollack wrote in the email that she began deliberating about her retirement last fall, but several events forced her to postpone the announcement.

”I am writing today to announce that this will be my last year in that role, and that I will retire on June 30. It is only after extensive reflection that I have determined that this is the right decision,” wrote Pollock. “Indeed, I began deliberating about this last fall, and made the decision over the December break; but three times, as I was ready to act on it, I had to pause because of events on our and/or on other campuses. But continued delay is not in the university’s best interests, both because of the need to have sufficient time for a smooth transition before the start of the coming academic year, and because I do not want my announcement to interfere with the celebration of our newest graduates at Commencement in just a few weeks.”

Pollock didn’t give a clear reason for her retirement, but it comes at a time when almost every Ivy League institution has seen an increase in anti-Semitism on campus
