My research is in early Christian Greek and Latin literature. I am interested in the way early Christian texts convey historical, biblical, philological, philosophical, theological and scientific learning. I am also interested in the rhetorical and literary forms and transformations of these texts. I am pursuing, among others, the following themes and projects:

Julian of Aeclanum and the Second Pelagian Controversy

Having already published extensively on Julian of Aeclanum I am continuing to undertake research on various aspects of his life, writings, thought, and reception with the aim of producing a comprehensive study of this fascinating figure of late-antique Latin Christianity. My most recent publication in this area is in The Oxford Handbook on the Pelagian Controversy (2025) where I discuss Julian of Aeclanum as a biblical exegete.

Tatian, Ad Graecos / To the Greeks. Translation with introduction and commentary

I am currently writing the first ever commentary on Tatian's Oration to the Greeks, a second-century Greek apology, to be published in the series Kommentar zu frühchristlichen Apologeten (KfA; Freiburg: Herder).

Biblical and Philosophical Exegesis in Late-Antique Latin

This project emerged from a longterm project of comparing Latin and Syriac commentarial literature. It constitutes the Latin part of that project and consists of a number of ongoing projects on biblical and philosophical exegetes and their work including Jerome, Marius Victorinus, Victorinus of Pettau, Augustine, Pelagius and Julian of Aeclanum, and aims at a comprehensive study of late-antique biblical and philosophical exegesis in Latin.

Classical and Early Christian Historiography

This project is closely linked with my contribution (as sub-editor for Antiquity and Late Antiquity) to the Encyclopedia of the Medieval Chronicle-project. I am interested in the origins of historiography and in links between ancient classical, biblical, early Christian and late-antique historiography and between 'histories', 'chronicles' and other forms of historiography (including 'lives', 'letters', 'commentaries' etc.).

Themes in Early Christian and Late-Antique Intellectual Culture

I am also engaged in a number of studies, some already published, some awaiting publication, or being in preparation, which touch upon a variety of issues concerning religion in Late Antiquity, and especially Christianity:

Consolation: The transformation of a genre in Late Antiquity
Narrative, system and ritual in ancient cosmologies and their reception
Demons and demonology in early Christian thought and doctrine
Social ethical themes in early Christian and late-antique thought
Political concepts and their origins in late-antique thought
The role of memory in the formation of Christian identity
Education and intellectual formation in early Christianity
History and prophecy

Groups

I am a member of the following research groups and centres:

Centre for Late Antique Religion and Culture
