Dr Warren is Senior Lecturer in Biblical and Religious Studies at the University of Sheffield, and is a member of SIIBS, the Sheffield Institute for Interdisciplinary Biblical Studies. Warren directs the SIIBS research theme, Embodied Religion.
Warren completed degrees (BA, MA, PhD) at McGill University and from 2013–2015 held a postdoctoral position at the University of Ottawa funded by the Fonds de Recherche du Québec — Société et Culture. Warren has taught classes on early Judaism and Christianity, Koine Greek, ancient Mediterranean religions, and the early church. Warren’s primary research interests lie in the cultural and theological interactions among the religions of ancient Mediterranean, especially early Judaism and Christianity. In particular, Warren is interested in how shared cultural understandings of food and eating play a role in ancient narratives, including the Pseudepigrapha, Hellenistic novels, and the Gospels.
Warren's first book, My Flesh is Meat Indeed: A Nonsacramental Reading of John 6:51–58 (Fortress 2015), investigates how the Gospel of John makes use of Jewish, Christian, Greek, and Roman attitudes about sacrifice, divinity, and the consumption of human flesh in order to make claims about Jesus’ divinity.
Warren's second book, Food and Transformation in Ancient Mediterranean Religion, was published by SBL Press in 2019.
