Most of my research has explored connections between literature and sexuality from the late nineteenth century onwards. Particular interests include Henry James - my first book was Henry James and Sexuality (Cambridge University Press, 1998), D. H. Lawrence, queer theory and the history of literary representations of homosexuality.

I have recently completed a chapter on lesbian and gay fiction since 1970 for the forthcoming Cambridge History of Gay and Lesbian Literature, edited by Ellen McCallum and Mikko Tuhkanen. As a result of this work, and work I did for the Cambridge Companion to Gay and Lesbian Writing, which I edited and was published in 2011, I am currently planning more articles on gay and lesbian fiction since 1940. In addition, I am continuning to publish extensively on D. H. Lawrence: an article on Lawrence and Wagner is forthcoming in Textual Practice.
