Eva Surawy Stepney (she/her) is a PhD candidate in the Department of History at the University of Sheffield. Funded by the White Rose College of the Arts and Humanities (WRoCAH), her thesis explores the history of Obsessive Compulsive Disorder (OCD) and its intersection with post-war British clinical psychology. She is interested in the way in which psychological ideas of ‘evidence’ produce the conceptual architecture of OCD and the implications this has for understanding of psychic distress more broadly.
