I have published the books Duet and Dialogue in the Age of Monteverdi (UMI), Monteverdi, 'Orfeo' (Cambridge University Press), and Monteverdi, Vespers (1610) (Cambridge University Press). With Richard Wistreich (Newcastle University) I recently published The Cambridge Companion to Monteverdi (Cambridge University Press, 2007). I am currently working on a project with colleagues at Heidelberg and Rome, and with former students now lecturing on music at universities in Greece, to produce an online series of editions of Italian vocal music from the first half of the seventeenth century. I am also currently working on a bibliographical study of Monteverdi’s Selva morale e spirituale (1641). My edition of the second book of madrigals (1640) by Giovanni Rovetta (Monteverdi’s assistant choirmaster at St. Mark’s Venice) is available online (www.ascima.bham.ac.uk) and may be freely downloaded for study and performance. I have worked extensively with Anthony Rooley, Emma Kirkby and The Consort of Musicke, particularly on their series of recordings of Monteverdi madrigals, and with The King's Consort on recordings of Monteverdi's sacred music. For five years I was co-editor of the Oxford journal Music & Letters and remain a member of its editorial board.
