My research is currently focussed on two major projects: The Oxford Edition of the Sermons of John Donne (16 vols., 2013 - , OUP), of which I am General Editor; and Lancelot Andrewes: A Life (OUP, forthcoming). Both are deeply engaged in literary, religious, intellectual, and political history; textual criticism; biography; and the history of the book. My ongoing work on a private library bequeathed to Lincoln College in the eighteenth century is also generating talks and publications related to book collecting and reading among gentry men and women in early modern Oxfordshire.
