My primary research interests lie in the history of early modern London, though I teach over a broad range of early modern British and European courses. My current research ranges over a variety of issues in London history: charity, popular politics, taxation, and governance.
I was the Academic Editor of the Bibliography of British and Irish History, previously the Royal Historical Society Bibliography, of which I was General Editor from 1999 until 2010. This database aims to make bibliographic data on British History electronically available, and it is interoperable with a wide range of other online resorces.
I am Literary Director of the Royal Historical Society with responsibility for the Camden Series and the Transactions of the Royal Historical Society.
I am an Academic Adviser to the Records of Early English Drama project.
