Albrecht Diem has studied history in Düsseldorf, Tübingen and Utrecht. He received his PhD in 2000 from Utrecht University with a thesis on the late antique and early medieval monastic discourse on chastity and sexuality (published 2006 as Das monastische Experiment. Die Rolle de Keuscheit bei der Entstehung des westlichen Klosterwesens). From 2005-2007 he was a research fellow of the FWF-Wittgenstein project „Ethnic Identities in Early Medieval Europe“. He teaches at Syracuse University (NY) since 2007 (since 2011 as tenured associate professor). He was a fellow of the Pontifical Institute for Medieval Studies in Toronto (2001-2002), the Institute for the Studies in the Humanities in Madison, WI (2010-2011) and a member of the Institute for Advanced Study in Princeton (2015-2016).
His research focuses on the history of monasticism in Late Antiquity and the Early Middle Ages. He published on monastic rules, female monasticism, gender and sexuality, the history of emotions, pastoral care, and monastic education, and developed the Monastic Manuscript Project (earlymedievalmonasticism.org). As a member of the Wittgenstein-Project he worked on the interplay between monastic and ethnic identities. Currently he writes a book on the development of regular observance in early medieval monasticism.
