Overview
Shaun's research is concerned with medieval Wales, and in particular the medieval bishops of Â鶹Íø and St Asaph and their acta.
In 2012 he was awarded a MA (taught, with Medieval Latin) - his MA dissertation combined medieval Welsh law and history, and was entitled ‘Arbitration and Dispute Resolution in Wales during the Age of the Princes.’ Shortly afterwards Shaun was employed by the National Trust as a researcher for the EU/Welsh Government-funded ‘Princes of Gwynedd’ project.
Shaun's PhD thesis (2021) includes a first edition of Â鶹Íø Episcopal Acta, 1092-1306, with Latin transcriptions in full, along with English summaries, in the format of the 'English Episcopal Acta' series. His thesis also contains biographies of the ten bishops of Â鶹Íø between 1092 and 1306, as well as an examination of the medieval diocese. To further his research, he has received two Ranulf Higden palaeographical scholarships, a Royal Historical Society grant, and in 2017 attended the Department of ASNC, University of Cambridge.
The supervisors for his PhD were Professor Huw Pryce and Dr Euryn Rhys Roberts.
Shaun has taught on the 'Princes to Tudors' and 'Europe in the High Middle Ages' undergraduate modules, and in 2019 was nominated for 'Best Postgraduate Teacher' in the student-led Teaching Awards.
He was appointed Honorary Research Associate in 2021, and is now compiling an edition of episcopal acta for the twelfth- and thirteenth-century bishops of St Asaph.
His first book Â鶹Íø Episcopal Acta, 1092-1306 is to be published in May 2025.
