The center, which opened in September 1999, aims to facilitate public service on campus.
It remains unclear when or why the center's leadership has changed, although the center Web site states that a search committee began reviewing applications for the position in July.
When asked why he left the position, Nick Didow said the position of director is an at-will position, meaning it is subject to constant review from the provost.
Didow did not comment any further on why he left the position and suggested that the provost's office be contacted for additional information.
The Daily Tar Heel attempted to contact Provost Robert Shelton, but Shelton was out of town Thursday night and could not be reached for comment.
Cindy Wolf Johnson, associate vice chancellor for student learning, also declined to comment on the circumstances surrounding Didow's departure.
Wolf Johnson, who is heading the search for the new director, said about 40 or 50 applications have been submitted for the position. She said the committee has not set a definite timeline yet but would ideally come to a final decision by early October.
Applicants will be selected for phone interviews in about one week with campus interviews to follow. "We are looking for somebody who has a passion and commitment for public service," Wolf Johnson said.
The main responsibility of the Center for Public Service is to facilitate public service on campus by creating awareness, raising funds and collaborating with other campus groups.
