Petros Toulis is Assistant Professor of Dogmatic Theology at the Department of Social Theology and Religious Studies, School of Theology, National and Kapodistrian University of Athens.
He studied Theology at the Aristotle University of Thessaloniki (AUTh), where he also completed postgraduate studies in Dogmatic Theology with distinction. As a scholar of the Greek State Scholarships Foundation (IKY), he pursued further graduate studies at Holy Cross Greek Orthodox School of Theology in Boston (2006–2007), during which time he also attended courses in Roman Catholic Theology at Boston College. He received his doctorate from AUTh in 2013 with distinction, with a dissertation entitled The Created and the Uncreated in Theophanes of Nicaea: A Study of His Teaching on Creation.
He has completed four postdoctoral research projects:
- Theophanes of Nicaea’s Oration “Εἰς τὴν Πανάχραντον καὶ Παναγίαν, Δέσποιναν ἡμῶν Θεοτόκον” (“On the Immaculate and All-Holy, Our Lady the Theotokos”): A Patristic and Dogmatic Approach (Department of Theology, AUTh, 2014–2016).
- Interpreting the Hesychast Controversy during the Preparation of an Ecumenical Council: Theophanes of Nicaea and the Latin Archbishop of Constantinople Paul, as a research fellow of the Hellenic Institute of Byzantine and Post-Byzantine Studies in Venice (2019–2020).

- The Mystery of Repentance and Christological Dogma in Elder Joseph the Hesychast, within a research programme of the Special Account for Research Funds (ELKE) of AUTh (2025).
His research and publications focus on Dogmatic Theology, late Byzantine patristic thought, and Roman Catholic and Protestant theology. More specifically, his work addresses the interpretation of dogmatic texts, the doctrinal terminology of the Ecumenical Councils, the Hesychast controversy, the neptic tradition, and inter-Christian relations.
Since 2016 he has been a member of the research team of the Network for Textual and Hermeneutical Ecclesiastical Tradition at the Department of Social Theology and Christian Culture, School of Theology, AUTh. He is a member of the Greek Committee of Byzantine Studies and, since 2018, of the European Academy of Religion (EuARe).
