Most of my research has focused on the interplay between religion and popular politics in modern Ireland. My first book, Rituals and Riots: Sectarian Violence and Political Culture in Ulster, 1784-1886, examined the relationships between Catholic/Protestant rioting and the emergence of a divided political culture in the north of Ireland. I have also co-edited two volumes of essays on aspects of the modern Irish experience (with Danine Farquharson and Michael de Nie) and co-authored a book (with Mathieu Billings) entitled The Irish in Illinois. My latest book, Thomas Drew and the Making of Victorian Belfast, uses the public career of a populist Orange cleric to re-evaluate the history of nineteenth-century Belfast. It is set to be published by Syracuse University Press. I am a former President of the American Conference for Irish Studies and currently an international representative for the Society for the Study of Nineteenth-Century Ireland.

As a historian of the British Isles, I teach survey courses on Late Medieval and Early Modern England, Scotland and Wales, Modern Britain and Modern Ireland. In my upper division and graduate courses, I'm particularly interested in exploring questions of empire and nation, so most of my courses revolve around those broad themes.
