Tyler Sampson holds a Ph.D in liturgical studies from The Catholic University of America. He was most recently a lecturer at CUA and a senior lecturer and affiliate professor at Virginia Theological Seminary. His research focuses on the history and theology of Christian liturgy in the first millennium, particularly the developments and adaptations of the liturgy of the city of Rome. While at the ISM, he will expand on his dissertation research with a project entitled, “Ordo et Ratio: Ordering, Explaining, and Celebrating Liturgy in the Early Medieval West.” With this project he aims to deepen our understanding of this critical period of liturgical history by placing manuscripts of liturgical handbooks at the center. These understudied books, with instructions, commentaries, and other texts, were central to enacting the liturgical reform of the Carolingians and reveal the creativity and diversity of its implementation.
