Reader in Early Modern History, Director of Research
Overview
I am a historian of early modern religion, with a particular interest in reputations - how people came be to be seen as exceptionally wicked witches or as exceptionally devout, wonder-working saints. I have written widely on both Catholic Reform and the early modern witch-hunt, two subjects brought together by my first "love", the sixteenth-century Jesuit Martin Delrio who wrote an influential work of demonology. My next book The Basque Witch-Hunt: A Secret History examines one of Europe's most notorious witch-hunts and will appear in October 2024.

Teaching
I am primarily a historian of early modern religion. With my medieval colleague Paul Webster, I teach a new module on the History of the Supernatural which takes a long view on how Christians saw and engaged with supernatural events and creatures, from miracles to witches and werewolves. I also teach an advanced third-year module on the early modern witch-hunt.
Biography
I am Reader in Early Modern History at Cardiff University. I am very much an accidental transplant, both in the UK and in Wales but happy to call both places home.
I first came to Britain as a visiting graduate student in the spring of 2006. I then stayed to complete a second masters, for which I gained a distinction, and a doctorate (supervised by Robin Briggs) at Oxford University. My graduate studies were supported by the AHRC, the Fullbright Commission, the Royal Historical Society, and a Scatcherd European Scholarship from Oxford University. During my doctorate I held visiting fellowships at Princeton and Cornell University in the United States.
After completing my PhD early 2011, I held a number of temporary teaching and research posts, before moving to Cardiff in January 2016.
