My main fields of interest are in the areas of syntax and morphology in Amazonian languages, especially Panará (Jê) and Mỹky (isolate), two indigenous languages of Brazil on which I periodically conduct fieldwork. I have also done fieldwork with Mẽbêngôkre (Jê), and more sporadically with Tapayuna/Kajkwakhratxi (Jê), Kaiabi/Kawaiwete (Tupian) and Rikbaktsa (Macro-Jê).
As a syntactician, my research focuses on the morphosyntax of participants (case marking of core arguments, the syntactic status of obliques, the features that participate in cross-reference morphology, grammatical relations) and of interlocutors (interlocutor agreement, genderlects, honorificity, evidentiality, epistemicity). I also investigate the relationship between linguistic structure, speech practices and musical traditions, and how linguistics, ethnomusicology and ethnoarchaeology may allow us to obtain glimpses into the deeper history of Amazonian indigenous nations. Language documentation and revitalization have also become a central focus of my research as a linguist.
