My research centres on: historical approaches to psychology, the emotions, ethics, health and madness; philosophy and medicine in the Graeco-Roman world; and the enormously influential medical author Galen of Pergamon (2nd century AD). Alongside a range of scholarly publications in these areas, I am an active contributer to the Cambridge Galen Translations series, with two volumes already published and several more in progress. I have been funded for this research by the Wellcome Trust, at both Newcastle University and Birkbeck, University of London (project: ‘Galen on the Pulse)’; and also by the Humboldt Foundation and the Einstein Center Chronoi in Berlin. Themes include: the history of research on the mind and the brain; definitions of mental illness; medical and philosophical approaches to the emotions; ancient clinical and psychotherapeutic practice. I am preparing a book on Body and Mind in Ancient Thought for Routledge.

Alongside these main research areas I also have active interests in: techniques and texts of philosophical psychotherapeutics (Epictetus, Marcus Aurelius, Plutarch, Seneca); Plato and the Neoplatonist tradition; ancient pharmacology; the history of the book; drama and performance practice; Sanskrit and ancient Indian thought.
