Gabriel Radle specializes in early and medieval Christian liturgy, with a particular focus on the Mediterranean world. His research contextualizes the historical practice of Christianity through the comparative reading of liturgical manuscripts across traditions and by engaging these sources with visual and material culture, hagiography, homiletic literature, and legal documents, both canonical and civil. His publications include studies on marriage rituals in East and West, including a monograph on late antique and Byzantine weddings (forthcoming, Cambridge University Press), prayer books on Sinai, medieval rites of passage for children and adolescents, manuscripts of eucharistic texts, and the unique medieval religious history of Southern Italy. Radle has lectured internationally and held research fellowships at Yale University's Institute of Sacred Music, Dumbarton Oaks (Harvard University), the Hebrew University of Jerusalem, Princeton University, the Institute for Advanced Study, and the University of Regensburg (Alexander von Humboldt Foundation fellow).
