I am a historian of Europe of wide interests. My research has ranged across the period 1100-1600, through the exploration of themes in the religious culture of Europe. I am interested in inter-disciplinary encounters, and these have animated my work. I also enjoy disseminating history to diverse audiences all over the world.
