In 2012, her Naduhup studies expanded with a fieldwork grant from the Endangered Language Documentation Program (ELDP) providing funding for her work with Dâw in 2013.
[3] Her work is notably focused simultaneously on engaging in linguistic inquiry and producing community materials.
Epps has regularly collaborated with members of linguistic communities to create documentation of material culture (in the form of, e.g., instructional videos for making items), history (both of the distant past and of recent events as told from elders), family trees, rituals (when given the explicit permission of community members), and pedagogical and reference materials for the language(s) of a given group.
Epps, in collaboration with Claire Bowern, Jane Hill, and Patrick McConvell compiled data to create the Hunter-Gatherer Database, an NSF- and ACLS-funded project with the purpose of collecting "lexical, grammatical, and other data from languages spoken by hunter-gatherer groups and their small-scale agrarian neighbors."
