In 2010, Celenza took a leave of absence from Johns Hopkins^[5] to become the 21st director of the American Academy in Rome, succeeding Carmela Vircillo Franklin.^[10] He held this position until 2014, when he was succeeded by Kimberly Bowes.^[11] Following his directorship, Celenza returned to Johns Hopkins, where he became the chair of the department of classics from 2014 to 2016^[9] and the Charles Homer Haskins Professor of classics.^[12] For a year, he served as vice dean for humanities and social sciences in the Krieger School of Arts and Sciences. Celenza was subsequently appointed the vice provost for faculty affairs of Johns Hopkins.^[8] During his time at Johns Hopkins, he also assisted in the founding of the Alexander Grass Humanities Institute.^[13]
