My current research focusses on the formation of urban communities in late medieval Europe, with a special attention to the role of voluntary associations (guilds, confraternities and neighbourhood associations) in the emergence of networks of solidarity. I am working on a book project on this topic.

Furthermore, I am interested in digital mapping as a tool for historical research. Therefore, I initiated a project aimed at developing a historical Geographic Information System (GIS) for the Dutch town of Leiden.

Finally, following-up on earlier research, I have an interest in the history of noble elites in the medieval Low Countries.
