Alexander D鈥橝lisera is an interdisciplinary historian of medieval Europe, specializing in caves, stone, ritual, and religion. As a Visiting Assistant Professor at Boston College, he teaches core courses in both medieval European and early modern global history, including a new course called 鈥淭he History of the End of the World.鈥
Dr. D鈥橝lisera鈥檚 book project, Medieval Cave People: A North Sea Speleology, unearths the history of ordinary people in extraordinary underground environments across premodern Europe, with a focus on the real and imagined caves of the medieval north. As an interdisciplinary project that engages with vernacular texts, visual culture, Latin sources, and archaeological material, Medieval Cave People explores local human-cave entanglements across the North Sea region, while addressing the broader environmental and religious histories of medieval northern Europe and its connections with the Mediterranean world. 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.
Prior to his current appointment, Dr. D鈥橝lisera earned his Ph.D. in history from Boston College under the supervision of Professor Robin Fleming. From 2024 to 2025, he held the Charles W. Maus Graduate Research Fellowship in Karst Studies at the Cave Conservancy Foundation of Virginia. He also holds an M.A. in religion from Yale University, where he was a Marquand Scholar at the Divinity School, and a B.A. in history and classical studies from Bard College.
