Margaret Iversen is one of the leading international authorities in the field of art theory and contemporary art. Her first book was on one of the founders of Art History as a discipline: Alois Riegl: Art History and Theory (1993). Since then she has continued to write occasionally about the history of art history ('Retrieving Warburg's Tradition'), but has made her main areas of study psychoanalytic art theory, publishing Beyond Pleasure: Freud, Lacan, Barthes (2007). Her present and future research is devoted to the overlapping fields of photography and contemporary art. She was director of a large AHRC research project called Aesthetics after Photography (2007-2010), an interdisciplinary project in partnership with Diarmuid Costello of the Philosophy Department, University of Warwick. Other publications include a monograph on the contemporary artist Mary Kelly and an essay on the American painter Edward Hopper which appears in the catalogue of the 2004 Tate Modern exhibition of his work. Recently published work includes a book called Writing Art History (with Stephen Melville) and two articles, 'Analogue: Zoe Leonard and Tacita Dean' and 'Index, Diagram, Graphic Trace.'. She is currently working a book to be called Photography, Trace and Trauma.
