BA, New York University

MA and PhD, The Catholic University of America


Demetrios S. Katos is Dean of Hellenic College and Professor of Religious Studies. He has been on the faculty since 2000, offering courses in theology, history, and religion. Dean Katos is a Board Member of the Stephen and Catherine Pappas Patristics Institute of Holy Cross Greek Orthodox School of Theology, and he has served as Treasurer and Vice-President of the Orthodox Theological Society in America. From 2004-2010, he was a Lecturer in the Department of Theology at Boston College, where he taught courses in Eastern Orthodox theology.

Dean Katos devotes his research to the theology, history, and intellectual culture of Christian antiquity, and he specializes in early Christian spiritual and mystical traditions. His work and promise in the field was recognized by the academy in 2008 when he was named a Henry Luce III Fellow in Theology, and granted one of the premier fellowship awards for theological scholarship. His book, Palladius of Helenopolis: The Origenist Advocate (Oxford University Press, 2011), is the first monograph devoted to the life, work, and thought of the Christian bishop and author, Palladius of Helenopolis (ca. 363-430). Palladius is a key source of information for early Christian asceticism, spirituality, and pilgrimage, and for the lives of John Chrysostom, Theophilus of Alexandria, and Evagrius of Pontus. Dean Katos offers a new reading of Palladius’ widely influential Dialogue on the Life of St. John Chrysostom and Lausiac History by incorporating recent scholarship on late antique rhetoric and the Origenist tradition. He demonstrates that Palladius’ advocacy of his associates and of their shared theological vision has influenced Christian historiography and devotion for nearly 1600 years.
