Harvard’s Faculty of Arts and Sciences told departments it will dramatically reduce Ph.D. admissions over the next two years, with a 75% cut in the sciences and roughly 60% in the arts and humanities. The move, disclosed in internal emails and reported by The Crimson, follows a $113 million fiscal-year deficit and broader pressure on research funding. Departments must allocate far fewer slots, and some units could be left unable to admit new doctoral students. Faculty warned the reductions could undermine research capacity, graduate training and undergraduate instruction that depend heavily on doctoral scholars and teaching assistants.
