I read History and German as an undergraduate student at St Peter's College, Oxford, and at the University of Bonn, between 1997-2001. After a year working outside academia, I returned to undertake postgraduate work in the years 2002-06 at Oriel College, Oxford, and at the University of Freiburg. I was appointed as Junior Research Fellow in History at St John's College, Oxford, in the autumn of 2006, and held that post until my current appointment at Manchester in the autumn of 2009. I was promoted to Senior Lecturer at Manchester in 2015 and to Professor in 2025. I was first elected to the University Senate for the term 2018-21, and subsequently elected again for 2022-25 and 2025-28.

For the academic years 2012-14 I was Marie Curie Fellow in German History at the University of Freiburg. From February 2020 until August 2021 I was Alexander von Humboldt Fellow in German at the Berlin-Brandenburgische Akademie der Wissenschaften, and held a British Academy mid-career fellowship in the academic year 2022-23. I am UK PI of the AHRC/DFG-funded project ‘Werck der bücher’: Transitions, experimentation, and collaboration in reprographic technologies, 1440–1470 (2021-26), together with colleagues at the JGU Mainz and FAU Erlangen-Nürnberg.

Postgraduate Students

I welcome enquiries from prospective students considering research in many areas of later medieval European history (c. 1200-1520), but primarily intellectual history, religious and ecclesiastical history, the history of the German- and Dutch-speaking regions, cross-cultural contacts, and the history of the book (the codicological, palaeographical and material analysis of the medieval manuscript and early printed book). I would also be happy to supervise projects with a strong literary perspective that consider texts in German and Latin from the German Sprachraum in the period c. 1100-c.1550.

I am a scholar of late medieval intellectual, religious, cultural and literary history, and I work mostly on the German- and Dutch-speaking areas of Europe, but always considering them within a European framework. The challenge for me is the reconstruction of the intangible: the understanding of thought, opinion, and mentality in an age far removed from our own.

My book on Marquard von Lindau is an attempt to show that German intellectual culture and religious life in the period between the mid-fourteenth and the mid-fifteenth century was not stagnant and uninventive, but vibrant and genuinely radical. Marquard's name is totally unknown to a modern audience, but he was quite possibly the most widely read author in the German language before the Reformation. He is a measured, engaging, and interesting writer, with a genuine interest in those amongst whom he lived. I continue to write on Marquard, and have published a number of articles that explore different features of his work.

I am currently working on a long-term project to write the history of the literary spirituality of the upper Rhineland between the early fourteenth and the early sixteenth centuries, around the 'fixed point' of the convent zum Grünen Wörth (the 'Green Isle') in Strasbourg. This was founded in 1367 by a repentant merchant banker and noted mystical writer named Rulman Merswin, as a kind of lay monastery in which he, his wife, and their associates could shape the form of their own religious lives. It was incorporated four years later into the Order of St John (the Knights Hospitaller), and in the later Middle Ages became one of the most important centres for the transmission and production of literary texts in all of German-speaking Europe. In the existing scholarship these people are understood as a religious movement known as the 'Friends of God', but this is not true: my task is to grasp what was.

Many of my projects arise from the desire to know when, where, and how particular ideas were known, how those ideas circulated, and what contemporaries thought about them. Careful examination of medieval manuscripts is one way of getting at that kind of data, and much of my work is based on codicological work of this kind. I have also written in this vein on the European understanding of Islam in the later Middle Ages. The Islamic world was just as important for Europe in the Middle Ages as it is in the modern day. My interest lies in understanding exactly and precisely what was known and thought about Islam in different times and places in the medieval west, and how it came to be known. Not all of what was thought was as negative as one might expect. I have written a long article on this issue, starting with my old friend Marquard.
