My research focuses primarily on the political history of 13th- and 14th-century England. I recently published The Plantagenets: History of a Dynasty (London and New York: Continuum, 2010), and an article on the household knights of Edward II. I continue to serve on the editorial board of Fourteenth Century England. My longer term research goal continues to be a political biography of Henry de Lacy, earl of Lincoln (d. 1311).
