Christopher S. Celenza, dean of Georgetown College at Georgetown University and professor of History and Classics, has been named dean of the Krieger School of Arts and Sciences. Celenza’s appointment, which begins Jan. 4, is a homecoming: He first joined the Krieger School faculty in 2005 as a professor in what was then the Department of German and Romance Languages and Literatures. Celenza went on to hold several leadership roles at Hopkins, ultimately serving as vice provost for faculty affairs until he departed for Georgetown in summer 2017.
