"As I planned when I took on this interim position, and with the support of the Board of Trustees, I am returning to my role as Chief Executive Officer of Columbia University's Irving Medical Center, Executive Vice President for Health and Biomedical Sciences, and Dean of the Faculties of Health Sciences and Medicine and the Vagelos College of Physicians and Surgeons," Armstrong wrote in a statement published on the Columbia University website Friday.
Amstrong had stepped into the role after the previous president, Minouche Shafik, resigned following scrutiny of her handling of protests and campus divisions over the Israel-Hamas war.
The university's trustees appointed the co-chair of their board, Claire Shipman, as acting president while the search for a permanent replacement continues.
