Simon Cohn’s research focuses on issues related to diagnosis, contested conditions and chronic illness in the UK and other high-income societies. More recently, he has started to think about the manner in which social relationships affect health care in tangible, material ways; for example, how trust - and mistrust - gets 'done.' With a strong commitment to contemporary social theory, he is interested in how innovative social science might provide both critical insight and influence in aspects of contemporary biomedical practice.
