He earned a Ph.D. in English with an emphasis in Rhetoric and Composition at the University of Wisconsin-Madison. Dr. Casas researches in/visibility and rhetoric among marginalized people, as well as deliberation, civic participation, and writing in everyday life and contexts. His dissertation, “In/visibility, mobility, and making do in contemporary Latina/o migrant rhetorics,” explores the ways Latina/o migrants, many of whom are undocumented, are able to make a way and place for themselves in the U.S. through nuanced negotiations of visibility and invisibility, and how these result in greater mobility in spite of the many obstacles in their way.
