My main area of research is Christian-Muslim interactions across theology, philosophy, and literature. After completing my doctorate, I became a Mellon Foundation postdoctoral fellow at the American University of Beirut. I have also worked as a cataloguer of Syriac and Arabic manuscripts at the Hill Museum & Manuscript Library and was a British Academy Postdoctoral Fellow at Oxford. My first book, entitled Christian Thought in the Medieval Islamicate World, was published by OUP in early 2022.

Areas of interest for supervision

I would be interested in supervising PhDs in the following areas:

  • Christian-Muslim theological encounters in the Middle Ages.
  • Syriac literature (theology, poetry, historiography, canon law) in contact with Islam.
  • Arabic-speaking Christianity in the Middle Ages.
  • Christian encounters with Islamic philosophy.

Research summary

I primarily research the religious, intellectual, and social history of medieval Christian communities in Muslim-ruled lands. My interests cover a broad range of topics within the study of Christian-Muslim relations. These include historical theology, philosophy, history of science, and literature. I also work extensively with Arabic and Syriac manuscripts, since many of the works I study have yet to receive modern editions and translations.

My first book, Christian Thought in the Medieval Islamic World, is a study of ʿAbdīshōʿ of Nisibis (d. 1318) and his Christian apologetics against Islam. My book also covers a 600-year period of history—from the advent of Islam to ʿAbdīshōʿ’s lifetime—that saw the emergence of a distinct genre of Syriac and Christian Arabic apologetic literature. This genre, I argue, was central to how Christianity under Islam maintained theological continuity in the face of repeated challenges to its core teachings.  

Current research interests

In addition to theology, I am also interested in philosophy and science as fertile sites of Christian-Muslim exchange. I have published an article on the ways in which Syriac Christian philosophy was transformed by its encounter with Muslim thinkers, namely Avicenna and Fakhr al-Dīn al-Rāzī. I also have a series of articles in preparation on the Syriac reception of post-Avicennan thought in Gregory Barhebraeus (d. 1286). The occult sciences are another area where Christian and Muslim cultures came together in exciting (and unexpected) ways. In 2021, I published a detailed study on a little-known alchemical treatise by ʿAbdīshōʿ of Nisibis and his use of both Christian and Islamic sources. Despite my training as a medievalist, I occasionally foray into more modern periods of Christian-Muslim encounter, having written an article on Arab Christian scribal practices at the dawn of print.

Project activity

I am currently collaborating with colleagues on two major book projects. The first is an annotated translation of the historical section of the Book of the Tower (Kitāb al-Majdal) by ʿAmr ibn Mattā, an 11th-century chronicle of the patriarchs of the Church of the East. Our translation has been accepted for publication at Liverpool University Press’s Translated Texts for Historians (TTH) and will be a resource for students and non-specialists interested in the history of Christianity in Late Antiquity and the early Islamic period. I am also beginning a collaborative project to edit a handbook on the Syro-Arabic tradition. Among other things, it will examine historical interactions between the Arabic and Syriac languages and the emergence of a distinct Arabic-speaking culture and literature among Syriac-rite Christians in the Middle East.
