Research Interests

My primary research focus is on seventeenth-century Irish political, constitutional, urban and military history, from the Ulster Plantation to the Jacobite Wars, situated in a broad European contextual framework. My most recent book examined the Cromwellian conquest and settlement of Ireland and I was Principal Investigator on the 1641 Depositions project and the Down Survey of Ireland Project. I am currently part of the editorial team producing a new five-volume edition of Cromwell’s Letters and Papers for Oxford University Press.

Teaching and Supervision

I teach several modules on early modern Ireland. These include the Junior and Senior Freshman (levels 1 & 2) survey courses on Early Modern Ireland, 1500-1800. I also teach a List 2 Honors module on ‘The Troubles: Ireland, 1968-1998’ and a List 1 Honors module on seventeenth-century Ireland, ‘From Rebellion to Restoration’. In addition I teach on the interdisciplinary strand, ‘Imagining Ireland I-IV’, for the Irish Studies programme.  I welcome research students interested in most aspects of seventeenth-century Irish history.
