I am an intellectual historian with an interest in theological, philosophical, and scientific encounters between Christians and Muslims living in the medieval Islamicate World. I earned my doctorate at the University of Oxford in 2016, and have since held research and teaching positions at the American University of Beirut and the Hill Museum & Manuscript Library, Minnesota. I am currently completing a monograph based on my doctoral research on the anti-Muslim apologetics of the thirteenth-century bishop and polymath Abdisho of Nisibis.


My current research focuses on two interconnected areas: (i) the history of theological encyclopaedism among Syriac and Arabic-speaking Christians in the medieval Islamicate World and (ii) the Syriac reception of Avicennan philosophy. The first—theological encyclopaedism—examines a widespread genre of literature produced by Christian communities in the medieval Middle East: the summa theologica, or summary expositions of the Christian faith. These texts provide key insights into how authors articulated a Christian world view within a broader, non-Christian religious setting. The second—the Syriac reception of Avicennan philosophy—focuses on the impact of Avicenna’s metaphysics on the philosophical and theological oeuvre of Barhebraeus (d. 1285/6), a near contemporary of Thomas Aquinas and of comparable significance to the Syriac Orthodox tradition.


A further project involves the history of Arabic alchemy, in particular, the representation of the Christian as mediator of alchemical and occult knowledge in the pre-modern Islamic imaginary. Much of this work centres on an unedited alchemical primer attributed to Aristotle, of which I hope to produce a critical edition, translation, and study of its scientific and literary contexts.
