As Research Manager, I am responsible for enhancing the School’s research environment, facilitating the delivery of strategic research objectives, ensuring the management and analysis of data as required for internal and external reporting, and supporting the development and implementation of School Research Faculties. I administer all research-related activities, including the recruitment and management of the School’s postgraduate research students.

I also coordinate HST5900 History Internship, an undergraduate module that gives students the exciting opportunity to complete an internship placement with one of our local partners in the museum, public history, archival or education sectors. 

I completed my PhD at Royal Holloway, University of London in 2016 on the subject of ‘Miracles for the Mad: Representations of Madness in English Miracle Collections from the Long Twelfth Century’, under the supervision of Professor Peregrine Horden. My research explores how madness was distinguished and diagnosed as a condition of the mind and what effects it was thought to have on the bodies, minds and souls of sufferers whose miraculous encounters with madness (either as a divine punishment or as a condition from which they were miraculously cured) were recorded by monks in large collections of miracles attributed to the saints. I focus on the twelfth century, which has been identified as a ‘Medieval Renaissance’: a time of cultural change that saw, among other things, the expansion of England’s great cathedrals, the development of canon law, the emergence of the concept of purgatory, the rise of the universities, and the wide dissemination of Latin texts and translated Greek and Arabic works, which brought with them a wealth of new ideas. My first monograph on this subject was published by Routledge in 2019.
