Alexander D鈥橝lisera is an interdisciplinary historian of premodern Europe, specializing in caves, stone, ritual, and religion across the medieval North Sea world. As a Visiting Assistant Professor at Boston College, he teaches courses in the global history core from the perspective of environmental studies, eco-criticism, and the history of religion. From 2024 to 2025, he held the Charles W. Maus Graduate Research Fellowship in Karst Studies at the Cave Conservancy Foundation.
Dr. D鈥橝lisera鈥檚 book project, Medieval Cave People: A North Sea Speleology, c. 400-1200, unearths the history of ordinary people in extraordinary underground environments across the premodern North Sea region. Deploying archaeological and literary sources together with ecocriticism and landscape phenomenology, the book contextualizes local and regional human-cave entanglements within the broader environmental and religious histories of medieval Britain, Ireland, Scandinavia, and Iceland.
Dr. D鈥橝lisera鈥檚 scholarship has also appeared in postmedieval, the Eerdmans New Testament Apocrypha book series, and Foillseachaidhean Rannsachaidh Oilthigh Ghlaschu (the University of Glasgow Research Publications), among other venues. With colleagues in the United Kingdom, he is currently co-editing an international volume on premodern stone, provisionally titled Interdisciplinary Perspectives on Stone and Society from Prehistory to the Middle Ages.
Prior to his current appointment, Dr. D鈥橝lisera earned his Ph.D. in history from Boston College, having worked under the supervision of Professor Robin Fleming. He also holds an M.A. in religion from Yale University, where he was a Marquand Scholar at the Divinity School, as well as a B.A. in history and classical studies from Bard College.
