Dr Delfi Nieto-Isabel


Marie Skłodowska–Curie and IHSS Fellow and Lecturer in History



I'm a Marie SkÅ‚odowska–Curie Fellow, Lecturer in History and a Fellow at the Institute for the Humanities and Social Sciences. I'm currently working on my EU-funded project, ILLITTERATAE, which aims to research women’s role in the transmission of alternative religious ideas, focusing on communities of beguines across the medieval Mediterranean. I co-lead the Time & Temporalities Research Cluster at the School of History and the international Blurred Boundaries of Religious Dissent Research Initiative, and I'm a member of the organizing committee of The Other Sister Project ( based at the University of Toronto.
I completed my PhD at the University of Barcelona in 2018, focusing on the application of Social Network Analysis to the study of dissident religious movements in the Late Middle Ages, and was a Research Associate and Visiting Lecturer in the Women's Studies in Religion Program at Harvard Divinity School in 2021-22.
