Mante Lenkaityte Ostermann is a Senior Researcher in the Department of Patristics and Church History at the Faculty of Theology, University of Fribourg. She has been affiliated with the University of Fribourg since 2007, initially as a graduate assistant, then as a doctoral assistant and lecturer, and currently as a researcher working on significant Swiss National Science Foundation (FNS) projects. Dr. Lenkaityte Ostermann earned her doctoral degree in Classical Philology from Vilnius University in 2007. Her academic journey has been deeply rooted in patristic studies and early Christian history, with a particular focus on Late Antiquity. Her research expertise spans several interconnected areas within early Christian studies. She specializes in ancient monastic literature, with particular attention to figures like Eucher of Lyon and John Cassian, as well as monastic rules. Her work also examines canonical sources and patristic exegesis, exploring how early Christian writers interpreted scripture. A significant portion of her recent research investigates the complex dynamics of religious identities and cohabitation in Late Antiquity, examining how different religious communities interacted, competed, and sometimes shared spaces during this transformative period. Her scholarly approach combines textual analysis with historical contextualization to reveal the nuanced ways religious identities were constructed and maintained. Dr. Lenkaityte Ostermann's extensive publication record demonstrates a consistent scholarly trajectory focused on the intersection of religious identity, textual interpretation, and communal practices in early Christianity. Her work reveals particular expertise in analyzing how early Christian writers constructed religious boundaries while simultaneously engaging with surrounding cultural and religious contexts. She has made significant contributions to understanding the development of monastic spirituality and its relationship to broader ecclesiastical structures, particularly through her examination of key texts like the Opus imperfectum in Matthaeum. Dr. Lenkaityte Ostermann has been actively involved in major research projects funded by the Swiss National Science Foundation. She was a member of the FNS-Eccellenza project on religious competition in Late Antiquity (2019-2022), directed by Assistant Professor Francesco Massa. Currently, she is contributing to another FNS project directed by Professor Franz Mali, which focuses on preparing the critical edition, French translation, and commentary of the anonymous work Opus imperfectum in Matthaeum .
