A.C. Koch is a writer, editor, and musician who teaches English as a second language at a university in Zacatecas, Mexico. Originally from Colorado, he has been traveling and working overseas since graduating with an Art History degree from the University of Colorado at Boulder. Experiences living in France, England, Korea, Hong Kong, and Mexico have provided a wealth of material for his fiction.

His story "The Only Cuauhtémoc in Town" was selected by Robert Olen Butler to take first place in the 2003 Raymond Carver Short Story Award, while his fiction has seen print in the Mississippi Review, Nighttrain, In Posse Review, and Exquisite Corpse. His own Spanish translation of his story "Río Muerto" won first place in a literary competition organized by El Sol de Zacatecas. Koch was subsequently commissioned by the Zacatecas Institute of Culture to create a production for the city's annual street theater festival. The production, adapted from his short story “Babel,” was presented as the closing spectacle of the festival in the old town plaza.

Koch co-edits a multilingual literary/arts journal, Zacatecas Review, the online manifestation of a quarterly print journal he founded in the early ‘90s. Koch moonlights as a guitarist in a jazz combo, and is a co-founder of the recording studio Estudios Viraje, where he works with local musicians to produce radio spots, demo albums, spoken-word poetry recordings, and multimedia projects.
He lives in Zacatecas, Mexico with his wife Fátima and five-year-old son, Nicholas. He maintains a daily writing routine, and is at work on a new literary thriller set in Paris, South Korea and the American suburbs.
