Major completed collaborative projects include the online and print New Oxford Shakespeare Critical Reference and Modern Critical editions of Shakespeare’s complete works. I was one of the General Editors of these volumes, with particular responsibility for the original-spelling Critical Reference edition. In addition, I edited some of the most textually challenging texts, including Hamlet and King Lear.
Previous to this, I was an Associate General Editor and major contributor to Thomas Middleton’s Collected Works. I have also edited Richard III and Timon of Athens for the Oxford Wold’s Classics series, and Sir Thomas More for the Arden Shakespeare.
I am a General Editor of the ongoing Arden Early Modern Drama, a parallel series to the Arden Shakespeare that publishes non-Shakespearian drama of the early modern period.
I am also a member of the Editorial Committee of the Malone Society, and have overseen a number of their editions now in print.
I am on the Advisory Board of Shakespeare Internet Editions, the prime example of a freely-available online digital Shakespeare edition and resource. I also serve on the Advisory Board of several journals including Shakespeare Survey.
I have published articles on textual studies in various leading scholarly journals, and am currently developing a research project on Sir Edward Dering’s 1623 manuscript adaptation of Shakespeare’s Henry IV plays.
