After a PhD (2014) focused on medieval history and data mining, Nicolas Perreaux completed three postdoctoral fellowships in France, Germany and Belgium. In 2019, he obtained a stable position as a research engineer at the University of Paris 1 Panthéon-Sorbonne. Since 2008, he has participated in numerous projects involving the creation and analysis of medieval text corpora: the CBMA, the Dictionnaires topographiques de la France Médiévale, the ANR Espachar, the ANR Charcis, the ANR Pocram, but also more recently the COST project Worlds of Related Coercions in Work (WORCK). He is also the director of the Cartae Europae Medii Aevi (CEMA) project, which is the largest database of medieval diplomatic documents to date. At the same time, he has taught at the University of Burgundy, while delivering training courses on numerical methods applied to (medieval) history in France, England, Spain, Switzerland, Germany and Belgium. He is currently working on artificial intelligence methods applied to metadata creation, lexical processing of large corpora, and semantic modeling.
