Sergio Gorostiaga is a journalist, writer, educator, and political activist. He fled Argentina as a teenager in 1978 after the military dictatorship kidnapped his brother, Pablo. Living in exile, he worked as a street vendor in Spain for many years and later as a journalist. His book La Demora is a product of the writing he did during the dictatorship and his exile thereafter. Many of the 41 poems were later edited, rewritten, or expanded upon and were released by the Argentine publisher "Libros de Tierra Firme" in 2001. They are as much a reflection of exile, homelessness, and loss as they are a portrait of the ways the violence and terror of the 1976-1983 Argentine military dictatorship disrupted and ended many lives. Currently, Sergio finds himself focused on publishing an anthology of his journalism throughout Latin America as well as two historical books he has written chronicling the history of Panama and Columbia from colonial period to the twentieth century.

He lives in Buenos Aires, Argentina.
