My research focuses on understanding the nature of grammatical variation, acquisition and change, principally in the Romance languages. Within Romance, I work on both standard and non-standard Romance varieties, with particular interests in French, Occitan, Spanish, and the languages of Italy. Much of my work to date has focussed on the early history of the Romance languages, which constitutes a missing link in our understanding of how Latin changed into the Romance languages spoken today.

My most recent book, Syntactic Change in French, appeared with Oxford University Press in 2021 and charts the grammatical evolution of French from Latin through to the present day, in light of recent advances in our understanding of the nature of grammatical variation and change. I have also co-edited a major Oxford University Press handbook entitled Rethinking Verb Second (2020, OUP) as well as two further volumes: Variation and Change in Gallo-Romance Grammar (2020, OUP) and Continuity and Variation in Germanic and Romance (2021, OUP). A monograph on word order in Medieval Romance languages appeared in 2018 with OUP, entitled Verb Second in Medieval Romance.

My current research is focussed on the internal and external factors driving the morphosyntactic differentiation of the Romance languages from the medieval period to the present day, with a particular emphasis on why certain grammatical properties remain stable whereas others change over time, often rapidly; the project combines insights from theoretical diachronic syntax and functional-typological research with research on language acquisition and language contact. I am writing a major monograph on this topic from 2023 onwards entitled Syntactic Stability and Change in Romance, which is funded by a Philip Leverhulme Prize. I am also in the process of editing the c.1000-page Oxford Handbook of Syntactic Cartography.


At undergraduate level, I teach a broad range of papers within the Oxford course, including French language and linguistics at all levels, comparative Romance linguistics, historical linguistics, and Italo-Romance linguistics. I also teach the General Linguistics course both at Prelims and FHS level for St Catherine's and St John's.

Graduate Teaching

My recent doctoral students are Andrew Lloyd (2017-2022, The Microvariation of Post-verbal Negative Particles in Old Gallo-Romance: A Comparative Study) and Wyn Shaw (2020-2023, Word Order and Information Structure in Early Modern French). Students completing Masters theses under my supervision have, in recent years, worked on the theoretical underpinnings of our assumptions about the left periphery, Stylistic Fronting phenomena in Old French, Old Gallo-Romance negation, and the relative complexity and simplicity of creoles.

I am always keen to hear from prospective graduate students working on topics within synchronic or diachronic Romance morphosyntax, as well as general topics within formal syntax, historical linguistics, French linguistics, and comparative Romance linguistics. My teaching at Masters level includes historical linguistics, French linguistics (both synchronic and diachronic), Romance linguistics, and formal syntax.

Access and Admissions

I have interests in school governance and educational policy and am happy to participate in access and admissions initiatives both within Oxford and elsewhere. As well as coordinating the Medieval and Modern Languages Faculty's access and outreach strategy as Director of Schools Liaison and Outreach, I am currently coordinating a national project to improve the number of care-leavers accessing Higher Education.

I believe it is important for those of us in Higher Education to participate actively in education at all levels and have served as Vice-Chair of Directors of a Multi-Academy Trust and Vice-Chair of Governors at a Sixth Form College, as well as other Trustee and Governor roles within the education sector. I am currently a Governor of Abingdon and Witney College.
