Erik Kooper received both his MA and PhD degrees from Utrecht University, where he taught Old and Middle English until his retirement in 2007. Since then he has regularly taught courses and given guest lectures both at his own university, the Nijmegen Radboud University, and abroad, e.g. in Sofia (Bulgaria) and Ghent (Belgium). His main research interests are in the fields of Middle English literature and culture, and medieval historiography. In 1999 he founded the Medieval Chronicle Society (of which he was International President until 2008), and its yearbook The Medieval Chronicle, of which he is still the general editor, and of which vol. 14 appeared in 2022.
His other publications include an edition of four Middle English romances for the American TEAMS series (2006), an edition of the Middle English poems Arthur (2011) and St Teilo (2016), and several articles on Middle English historiographical texts.
