I spend a fair amount of my time conducting fieldwork among the Tuparí, an indigenous people who reside in the Brazilian state of Rondônia. Their language belongs to the Tuparían branch of the Tupían family. (To read more about the group, click here for English or here for Portuguese.)
In 2016 I published a paper in the International Journal of American Linguistics on nasal harmony and phonotactic constraints in Tuparí phonology. You can access this article here. Special thanks go to Geovane Kamarom Tupari, a resident of Trindade village, for providing the .wav files which accompany the article. Please note that the appendix to my dissertation provides fresh data on Tuparí phonetics and phonology.
An article on the restriction of negation in Tuparí to the nominal domain has been published in the June 2018 issue of Language. This article is available for download here. Approximately ninety mp3 files provided by Sergio Tupari (from the village of Serrinha) accompany the published version and are available at this link. (Contact me over e-mail if you don't have access to Project MUSE.)
My dissertation, defended in June 2018, provides an extensive description and analysis of Tuparí grammar -- the most complete yet produced for the language. It's available for download on LingBuzz.
Current projects include: evidentiality and resultativity in Tuparí (building upon chapter six from my dissertation); the relationship between internally-headed relative clauses and the extensive use of direct quotation in Tuparí discourse; and the interaction between ergative-absolutive and nominative-accusative properties in Tuparí morphosyntax. Contact me for drafts, handouts, and the like.
