His interests include modern theatre; modernism and media; and relations between technology, science, and the arts. His book The Nervous Stage: 19th-century Neuroscience and the Birth of Modern Theatre explores historical intersections between the performing arts and the neurological sciences and traces the construction of a “neural subject” over the course of the nineteenth century. It was published by Oxford University Press in 2017. His previous book, The Total Work of Art: From Bayreuth to Cyberspace (Routledge, 2007), presents a history and theory of modern artistic synthesis, placing such diverse figures as Wagner, Moholy-Nagy, Brecht, Riefenstahl, Disney, Warhol, and contemporary cyber-artists within a genealogy of totalizing performance.
