I am a diachronic linguist whose work has a quantitative and computational bent. My main interests concern sound change and morphosyntactic change. Broadly speaking, I am interested in the pressures that interact to shape the synchronic profiles of languages, with a focus on languages of Central, South and Southeast Asia. I use a wide range of tools in my approach to these issues. A large part of this work is carried out in the framework of phylogenetic comparative methods; an equally large part involves the development and refinement of admixture models, which provide an explicit means of addressing language contact.
