I am a historical linguist whose work has a quantitative and computational bent. Broadly speaking, I am interested in the pressures that interact to shape the synchronic profiles of languages, with a focus on the Indo-Iranian subgroup. My core research questions involve phonological and morphological change, as well as typological change. 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.
