At �󷢲�Ʊ since 2001; before then I was a lecturer on history and literature, Harvard University, 1998-2001, and visiting lecturer in history, University of Massachusetts at Amherst, 2001; in fall 2005, I spent a semester as a visiting assistant professor at Harvard.

Medieval European history: I teach a variety of courses including introductory courses on medieval Europe and on the Crusades, as well as an introductory course on modern Britain; 300-level courses on medieval Italy and on late medieval England; and a seminar.  I also teach Core Western Traditions.  I've led the London History Study Group many times, most recently in spring 2018.
