Everyone knows that if you're an academic, it's essential to have books behind you in your photograph!
I'm sometimes asked if I've read all of them (and there's lots more). The answer is - most of them! However, some are reference works which are not intended for cover-to-cover reading, and some are books that I've written.
My main interest is religion - particularly Christianity and minority religions, which are often pejoratively called "cults". My particular focus is on Jehovah's Witnesses.
I studied philosophy and theology and the University of Glasgow and obtained my doctorate at Oriel College, Oxford.
I have taught at several British universities, becoming Head of Religious Studies at the University of Wolverhampton in 2001. I am currently Honorary Research Fellow in Contemporary Religion at York St John University and the University of Birmingham.
