Sr. Theotokos received a B.A. in Ancient Studies (Hellenistic Judaism) from Columbia University in New York; and a M.A. in Church History (Early Medieval), an M.Phil. and a Ph.D. in Church History (Patristics) from the Catholic University of America, School of Theology and Religious Studies (2022). She wrote her doctoral dissertation on the temporal function of Pascha (Passover/Easter) in the writings of Eusebius of Caesarea, demonstrating especially how it served as a bridge between sacred scripture, Jewish history, and the formation of Christian liturgical time.

Sr. Theotokos has published on the reception of Augustine’s De civitate Dei in the Itinerarium mentis in Deum of Bonaventure (Traditio, 2020), and on Philo of Alexandria’s adoption of a Spartan liturgical practice to describe Pascha to Hellenized Jewish (and non-Jewish) readers (Studia Patristica, 2021). In addition to numerous published book reviews, she has also presented her research at the International Conference on the Science of Computus in Late Antiquity and the Middle Ages (Galway), the Annual Meetings of the North American Patristics (NAPS, Chicago), the International Conference in Patristic Studies (Oxford), the Patristics Medieval and Renaissance Studies Conference (PMR, Villanova), and the Italian Cultural Society (Bethesda, MD). She has also served on planning committees and facilitated various academic conferences and seminars, including “Byzantine Monasticism: Past and Present” (Institute for the Study of Eastern Christianity, Washington, DC, 2020); “Treasures New and Old—Christian Culture and Cultures in the Patristic Age” (CUA, 2019); and co-founded the “Graduate Symposium on Patristic Receptions in a Modern and Postmodern Age” (CUA, 2018-2020). Sr. Theotokos is a member of the North American Patristics Society.

As a religious sister of the Institute Servants of the Lord and the Virgin of Matara (SSVM), Sr. Theotokos has also mentored extensively in the field of women’s education and consecrated life. She taught Latin, Introduction to Liturgy, and the History of Modern and Contemporary Philosophy in the house of studies of her own congregation for over fifteen years, as well as providing course design and instruction for a summer formation program for Hispanic women religious serving in the Catholic Church in the United States (“Esposas de Cristo, Hijas de la Iglesia,” CMSWR). In 2016, Sr. Theotokos participated in the launch of the GIVEN Forum, a leadership program for young Catholic women, and has returned to speak in subsequent annual meetings (now the GIVEN Institute). She has also recently published on contemporary consecrated life in New Faces, New Possibilities: Cultural Diversity and Structural Change in Institutes of Women Religious, edited by Thomas Gaunt, SJ and Thu T. Do, LHC (Collegeville, MN: The Liturgical Press, 2022). In 2011, she served as a panelist for “Call and Response: How American Catholic Sisters Shaped the Church since Vatican II,” at the Fordham Center for Religion and Culture (Fordham University, New York December, 2011).

Sr. Theotokos currently resides in Italy and carries out research on the Eusebian Gospel Canons.
