Areas of interest
My research interests include the papacy, the crusades, Jewish-Christian relations, heresy and dissent. I am also more generally interested in the medieval Church, religious belief and political ideas in the High Middle Ages (eleventh-thirteenth centuries).
I am a lecturer for the Graduate Centre for Medieval Studies and contribute to the core model Researching the Middle Ages. For the taught M(Res) in Medieval Studies I offer Options on The Crusades, The Papacy in the Middle Ages, Heresy in the Middle Ages, Christian-Jewish Relations in the Middle Ages and Minorities in the Middle Ages. I can also supervise Options on Medieval Monasticism, Christian Hagiography and Medieval Christian Spirituality. I also supervise dissertations within these areas of expertise.
I am happy to supervise any Ph.D. student with interests in the crusades, the papacy, ecclesiastical history, heresy and dissent, Christian-Jewish relations and medieval minorities. I currently have four Ph.D. students working respectively on southern French culture at the time of the Albigensian Crusade, the implementation of canon law in medieval Livonia (SWW DTP award), the Dominicans in the Holy Land, and the reign of Philip I of France (University of Reading Regional Bursary). Two Ph.D. students recently completed Ph.D. theses on the Cathar heresy and medieval debates about poverty. I also act as a Ph.D. monitor and examiner. I welcome Ph.D. applications within my areas of expertise.
I am willing to offer language courses at MA level in Classical Greek and Classical and Medieval Latin.

My book The Papacy and Crusading in Europe, 1198-1245 (Continuum, 2009) examines the papacy's authorisation of crusades against heretics and political enemies in Europe during the first half of the thirteenth century.
My book The Cathars and the Albigensian Crusade: A Sourcebook, ed. C. Leglu, R. Rist and C. Taylor (Routledge, 2014) brings together a rich and diverse range of medieval sources to examine key aspects of the growth of heresy and dissent in southern France in the twelfth and thirteenth centuries.
My book Popes and Jews, 1095-1291 (Oxford University Press, 2016) examines the papacy's relationship to Jewish communities in western Europe in the High Middle Ages.
Recent articles have explored aspects of papal policy with regard to crusading and the papacy's treatment of heretics and Jews in the High Middle Ages.
