David Roland Aers (born 3 October 1946) is James B. Duke Professor of English, historical theology and religion at Duke University. He has published widely on literature, sacramental culture and ideology in medieval and Renaissance England. He did undergraduate study at Cambridge University and earned his doctorate at University of York. He is a former editor of the Journal of Medieval and Early Modern Studies. His most influential work traces the influence of the Church Fathers in late medieval and early modern poetry and culture to work out questions of politics, gender, and social ethics.
Aers taught at the University of East Anglia before going to Duke in the mid-1990s. In 1998 he was awarded the Trinity College Distinguished Teaching Award. In an interview that shortly followed the award, he is quoted as saying, "My work moves between literature, theology, politics and history. The academic parceling up of these subjects can become an impediment to studying what I want to study, so that's the motive for interdisciplinarity. When I think about ethics, I can't help but think about politics. When I think about my Christianity, I'm also thinking about social justice. The questions I'm asking go directly across what have grown up as disciplinary boundaries within the modern academy."
