My research interests include phonological typology, language change, and linguistic complexity. I am particularly interested in rare and/or complex phonological phenomena, and investigate these in samples that include language families and regions which are traditionally underrepresented in our field.

I graduated from University of New Mexico in May 2017 with a Ph.D. in linguistics. My dissertation, entitled "Highly complex syllable structure: a typological study of its phonological characteristics and diachronic development," is a cross-linguistic study investigating the properties of and motivations behind rare syllable patterns in which long sequences of consonants occur.

At DDL I am working on a project entitled A typological investigation of the role of morphology in syllable complexity. This project explores interactions between morphology and syllable patterns in a diverse language sample, with the aim of addressing how different morphological processes and strategies may contribute to both synchronic variation in syllable complexity and the diachronic development of complex phonotactics.
