Ferreira graduated from Georgetown University, and she is interested in colonial and postcolonial indigenous writers. For many years, Ferreira has collaborated with Wayuu writer Estercilia Simanca, and she dedicated two chapters of her PhD dissertation to her work. To professor Ferreira, indigenous literature has been, from the fifteenth century to this day, not just a way to preserve indigenous traditional stories and cultures, but also a form of resistance to colonization. She is also a regular contributor to the Colombian magazine Razón Pública.
