In August 2012, Edōsdi defended her doctoral dissertation, Hedekeyeh Hots’ih Kāhidi – “Our Ancestors Are In Us”: Strengthening Our Voices Through Language Revitalization From A Tahltan Worldview. Her dissertation employed a Tahltan research paradigm and spoke to the ways in which the voices of her people can gain strength and healing through the revitalization of their Tahltan language. Upon the completion of her doctoral degree, Edōsdi was hired by the Tahltan Nation to take on the position of Tahltan Language and Culture Lead. Her doctoral research guided the development of a language governance structure and a language revitalization plan, which focuses on programming, documentation, and training and professional development. This 64-min documentary, Dah Dẕahge Nodes̱idē - “We Are Speaking Our Language Again”, focuses on the language revitalization work that the Tahltan Nation has been carrying out since 2012.
