My present research revolves around the history - especially the history of ideas and ideologies - of empire, its aftermaths and legacies. My main focus has been on British imperial history, including the role of imperial questions in domestic British politics; but my writing also involves a strong comparative element, which embraces a growing interest in ideas about American 'empire' today. Much of my recent and current work engages with the very concept of colonialism and associated terms, including reflection on and probing of the limits, the uses and indeed the abuses of the concept itself. Much, too, addresses broad theoretical and comparative questions about anti- and post-colonialism. I'm currently completing three interrelated books: on the intellectual consequences of decolonisation, on anticolonial intellectuals, and on representations and legacies of late-colonial violence.
