Hérold Pettiau studied history at the Université Libre de Bruxelles, where he specialised in medieval history with a focus on Late Antiquity and the early Medieval period, and at the University of Cambridge where he specialised in early Medieval Insular history and did his doctoral research within the Department of Anglo-Saxon, Norse and Celtic. Holder of a Ph.D awarded in 2002, he has been working at the University of Luxembourg as a Postdoc since 2004, then as Research assistant since 2007 as member of several projects on Medieval Lotharingia and on source-editing. He is currently a Research scientist (Maître assistant) working within the Institute for History.

His main fields of research and interest include the history of the county of Luxembourg in the 13th and 14th centuries, and the editing of sources pertaining to that period; the political organisation of the Carolingian and Ottonian periods, particulary in Lotharingia; as well as monastic history, with a focus on the Abbey of Echternach in the early and central Middle Age.
