My main research interest is in Latin linguistics, where I have published on phonology and metre, morphology, syntax, and semantics and pragmatics. I teach Latin and Greek philology, Indo-European linguistics, and morphosyntactic typology.

I am currently on research leave, supported by the Leverhulme Trust (Major Research Fellowship, MRF-2022-031). While on leave, I am writing a book on syntactic problems in Plautus and Terence. Until I return from leave in MT 2026, I am not taking on new students, except doctoral students working on early Latin.

I have written the following books:

- The Early Latin Verb System: Archaic Forms in Plautus, Terence, and Beyond (OUP 2007);

- Plautus: Comedies (Loeb Classical Library, 5 vols., HUP 2011-13);

- Varro: De lingua Latina; Introduction, Text, Translation, and Commentary (2 vols., OUP 2019);

- Latin Linguistics: An Introduction (De Gruyter 2024).
