Rombert Stapel (1983) studied Medieval History at Leiden University. He graduated in 2008 on a prosopographical study of the priest-brethren of the Teutonic Order in the Utrecht bailiwick (1350-1600) and continued to work as a PhD at the Fryske Akademy. In 2017, he defended his PhD thesis cum laude (with distinction) at Leiden University. This resulted in a monograph published in 2021 with Routledge: Medieval Authorship and Cultural Exchange in the Late Fifteenth Century. The Utrecht Chronicle of the Teutonic Order. 

He is currently working as a senior researcher at the IISH on themes related to the socioeconomic, demographic, and environmental history of the medieval and early-modern Low Countries and geo- or spatial humanities. He also coordinates geohumanities research at the KNAW Humanities Cluster. Amongst others, he has contributed to the projects Global Collaboratory on the History of Labour Relations 1500-2000, The Historical Dynamics of Industrialization in Northwestern Europe and China, 1800-2000, and Common Language for Accessibility, Interoperability, and Reusability in Historical Demography (CLAIR-HD) for which he is project leader together with Rick Mourits.

Between September 2020 and December 2022 he has been leading the NWO-funded project '(Re)counting the uncounted. Replication and Contextualisation of Premodern Dutch and Belgian Population Estimates (1350-1800)'. First results will become available in 2023.
