I am Assistant Professor of Medieval Mediterranean History. My research focusses on landscapes and societies that experienced religious and political expansions and, as a consequence, were characterised by considerable degrees of transcultural contacts and communication.

I studied History and Islamic Studies at Heidelberg University, and Jewish Studies at the Hochschule für Jüdische Studien. Before coming to Durham in September 2020, I held posts at the University of Konstanz, at Heidelberg’s Department of History and the Centre for Transcultural Studies. My research was supported by fellowships of the German Historical Institute in Rome, the DAAD and the Sonderforschungsbereich 1150 at the University of Münster.

My first monograph (Raumgeschichte einer Hauptstadt) is a study of how changing rulerships and dominant religions have transformed the built and social environments of Palermo as a Mediterranean capital city (c. 800 to 1200).

While I continue to be interested in the landscapes of medieval Sicily, I also want to dive into something entirely new: over the coming years, I intend to study the legal cultures and practises of decision making in the medieval Mediterranean. More specifically, I want to learn how groups and individuals in multireligious societies navigated between different legal arenas to seek advice or receive justice.

In addition, I am the co-editor of a commented anthology of Arabic and Latin primary sources. The project “Transmediterranean History: A Commented Anthology of Primary Sources” – headed by Prof Daniel G. König at Konstanz University – is an exciting, ongoing initiative that seeks to make Arabic and Latin primary sources accessible to researchers, students, and enthusiasts alike:

Research Interests
  • Landscapes and spatial history
  • Political and religious expansions
  • Legal cultures, legal advice and decision making
  • Religious minorities
  • Water, water-management and waterscapes
Research Supervision

I am happy to supervise students working on the medieval Mediterranean c. 800-1250, particularly on urban and landscape history; transcultural and interreligious contacts (Jewish-Christian-Muslim); legal and social history.
