I am a historian of late medieval Britain, especially of the political, military and cultural history of the fifteenth century. Before coming to Christ Church I worked at the universities of Kent, Oxford, Cambridge and the London School of Economics and was for nearly ten years a senior research fellow at the History of Parliament Trust. At Kent I was Faculty Director of Learning and Teaching for Humanities and I am particularly interested in developing learning technology in the classroom-based Humanities subjects. I am also programme director for the new BA (Hons) Medieval and Early Modern Studies.
Research and knowledge exchange
My research concentrates on the political culture of late medieval England and in particular on Lancastrian political culture (C.1399-1461). Previously I have worked on warfare and military culture in late medieval and early modern England, as well as government, administration and fiscal culture (particularly in regard to the reign of Henry VII).
I have appeared regularly on TV and radio commenting on aspects of fifteenth- and sixteenth-century history, most notably BBC2's The Real White Queen and BBC Radio 4's In Our Time.
I currently supervise three research students who work on the Lancastrian Archbishop Kemp, popular protest and communal memory in sixteenth-century Kent and the history of the Cray Valley, Kent, in the later Middle Ages.
Teaching and subject expertise
I teach on a range of late medieval and early Tudor topics and supervise research students on topics as varied as Archbishop Kemp and Reformation Canterbury. I am a Fellow of the Royal Historical Society and member of the editorial panel of the Fifteenth Century Series.
