My research brings grammatical patterns from lesser-studied languages to bear on key questions of linguistic theory. Many of my projects investigate the role of word-internal syntactic structure in the phonology and morphology of agglutinating languages. I focus mainly on A'ingae (or Cofán, ISO 639-3: con), an Amazonian isolate spoken by ca. 1,500 Cofán people in Ecuador and Colombia.
