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 am currently working on several articles relating to the household knights of Edward II, a topic on which I presented during a one-day conference on the reign of Edward II at the National Archives in London this past July. 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).
