I grew up in Pennsylvania before attending and graduating from the Virginia Military Institute.  I then earned my D.Phil. at Hertford College, Oxford.  I now live in Norwich with my wife and daughter.

I am currently pursuing a three-year Leverhulme-funded project entitled 'Crusading Diaspora: French Baronial Government in the Mediterranean, 1204-1287'.

Key Research Interests

I am interested in baronial government in the twelfth and thirteenth centuries and in exploring the ways in which barons imagined and implemented concepts of public good.  My research focusses particularly on the intersection of barons and aspirational Christian movements, such as the Cistercians or the crusades.

Teaching Interests

I currently teach the first-year 'Introduction to Medieval History' module, and will be teaching the third-year 'Crusades' module in the spring.  Beginning next year, I will be teaching the upper-level 'Apostles of Satan?' module on medieval heresy.

I cannot supervise doctoral theses, but I am very happy to assist with masters dissertations on a range of subjects including medieval barons, crusades, and heresy.
