Patrick Thomas is interested in language revitalization and the phonetics and phonology of indigenous languages of North America. He has worked with a member of the Gila River Indian Community on a lexicography of Akimel O'otham.

Currently, Patrick is a visiting faculty member at the University of Central Arkansas.
Natasha Warner is the director of the Douglass Phonetics Lab, and is Department Head and Professor in the Linguistics Department. Her research is in two areas: phonetics/psycholinguistics and language revitalization. In phonetics and psycholinguistics, She focuses on reduced, conversational, casual speech. She is interested in how much variability there is in the ways we produce and reduce or omit sounds, and in how listeners manage to understand speech despite that variability. How can a speaker decide to pronounce "but I was like..." as [brʌʒləiʔ], and how can a listener still find it completely intelligible? In language revitalization, She works with the Mutsun Amah Tribal Band of California. Mutsun hasn't had a native speaker since 1930, but there are huge quantities of written documentation on microfilm, and an active revitalization movement represented by the Mutsun Language Foundation in the community. With community and academic collaborators, Warner works on analyzing the written data, writing language teaching materials, and spreading the language in the modern community.
