Overview

I joined the School of History, Welsh History and Archaeology (as it then was) at Bangor in September 2007. I was awarded my Ph.D. by the University of St Andrews in 1998, worked for a time as a solicitor in the City of London, but returned to academia in October 2003. From then until the summer of 2006 I was employed in the History Faculty at Oxford University as a post-doctoral research assistant on a project to edit the charters and writs of Henry I (1100–1135).

I am a fellow of the Royal Historical Society, a member of the council of the Pipe Roll Society, and a trustee of the Allen Brown Memorial Trust. I am currently Director of the annual Battle Conference on Anglo-Norman Studies and editor of the conference proceedings, Anglo-Norman Studies.

My research focuses on the rule and government of Normandy and England from the tenth to the twelfth centuries. I published a monograph, Norman rule in Normandy, 911-1144, in 2017, and am currently beginning work on the subsequent period of Angevin rule in the duchy between 1144 and 1204. 

That research goes hand in hand with work on the rule and government of the Norman and Angevin kings in England, with a focus here on both the charters and writs that the various kings issued, as well as on the pipe rolls—the records of the annual audit of the king’s revenues.
