Mark Roosien is a lecturer in liturgical studies at the ISM and Yale Divinity School, focusing on Christianity in late antiquity. He was formerly an ISM fellow and more recently, served as admissions manager at the ISM. Prior to that, he held a Mellon post-doctoral teaching fellowship at Notre Dame University after receiving his Ph.D. in theology there in December 2018. Mark’s dissertation focused on “The Liturgical Commemoration of Earthquakes in Late Antique Constantinople: At the Intersection of Ritual, Environment, and Empire.” It analyzed the rite in historical and political contexts to expand the understanding of the formation of Constantinople’s stational liturgy, of time and the cosmos in the Byzantine Rite, and of the role of the liturgy in the political rise of Constantinople as the Roman capital in the East.
