Elaine Castillo writes fiction and criticism that refuse to explain themselves to a presumed white reader. Born and raised in the San Francisco Bay Area to a Filipino family, in a household where Pangasinan, Ilocano, Tagalog, and English all moved through the rooms, she set her work in the immigrant South Bay she grew up in and made its languages central rather than decorative. She studied at the University of California, Berkeley, and still writes about Milpitas, the town that raised her, as a real place rather than a backdrop.

Her debut novel, America Is Not the Heart (2018), follows Hero de Vera, a Filipina immigrant who arrives in the early-1990s Bay Area carrying the violence of the Marcos years and a family that has half-disowned her, and moves across three generations of Filipina women in a single household. The title answers Carlos Bulosan's classic America Is in the Heart; Castillo has called herself a daughter of that book, and she declined to italicize the Filipino her characters speak, refusing to treat their world as foreign.

The novel announced a major debut. It was longlisted for the Center for Fiction First Novel Prize and the Aspen Words Literary Prize, and named a best book of 2018 by NPR, the San Francisco Chronicle, Kirkus, and the Boston Globe. Reviewers read it as a family epic that channels a righteous anger about America's broken promises to the people it draws in.

Her essay collection How to Read Now (2022) turned the same intelligence on reading itself. Across nine essays she attacks the habit of treating nonwhite writers as native informants rather than artists, and the comfortable claim that literature automatically builds empathy, which she reframes as a way for readers to stay exactly where they are. She extends reading to film, television, and empire.

Her recurring subjects are diaspora and the myths families make of themselves, language and translation, colonialism, and the politics of who gets to be a universal reader. Named by the Financial Times one of the most exciting young people on the planet, and the author of a growing body of fiction and criticism, Castillo is, for a list of living Filipino authors, among the most intellectually ambitious.
