Delgado’s work often portrays the realities of the immigrant experience, with its attendant poverty, hardships, and love. In El Campo, Delgado’s poems about Mexican farmworkers and their families are accompanied by paintings by Simon Silva. Rosa Martha Villarreal, reviewing A Rush of Hands for Tertulia, noted the “muted images of personal sorrow and terrified wonder,” adding that Delgado “takes images from the community of shadows, the undocumented immigrants, and gives substance to their being.”
Delgado has been poet-in-residence at the University of Miami. He is a professor of creative writing, Chicano literature, and poetry at the California State University, San Bernardino.
