At its broadest my teaching covers art and architecture in Western Europe produced between c.400 and c.1400 AD. However my focused courses concentrate on works of art made the twelfth and thirteenth centuries, exploring issues of production, function and interpretation. These courses are largely based on material from Britain and France, with a particular consideration of surviving Irish artefacts. Modules currently on offer include To the Glory of God: The Art and Architecture of the Medieval Church c.1100-1220 Art in the Age of Chivalry The Art of Sanctity Introduction to Medieval Manuscripts I supervise post-graduate work on medieval art, and in particular illuminated manuscripts. PhD theses supervised include: Thirteenth-century Parisian Manuscripts of Peter Lombard’s Commentary on the Epistles (2014-present) Mythical legends or Moralising Commentaries? The Marriage of the Sacred and Secular in Fourteenth-Century French Arthurian Ivories and Illuminations (2014-present) The Faddan More Psalter (2012-present) A Hierarchical Image Processing Approach to Analysis of Early Medieval Manuscript Art (2012-15)

I am interested in the production of art and architecture in the High Middle Ages. Although my research concentrates on medieval manuscripts, I work with objects in a wide range of media. Particular areas of interest include links between art and education, the cult of saints in England and Ireland, and the illustration of historical subjects. In 2011-2015 I am co-ordinating a project looking at the illustration of history in the Anglo-Norman world (c.1100-c.1300), with particular emphasis on manuscripts. This project is funded by a Marie Curie Actions grant (FP7). In 2015 I began a project exploring the trade in western medieval manuscripts (principally in London) in the early twentieth century through the lens of the collection amassed by Sir Alfred Chester Beatty. The project is also attempting to trace the manuscripts that Beatty sold and gave away, and is working towards a digital reconstruction of his collection. Further information about the project can be found here. I am involved with the Trinity College Research Theme on Manuscript, Book and Print Cultures.
