Goñi was born in Washington, D.C. in 1953 and was raised in the United States, Argentina, Mexico, and Ireland. Since 1975, he has lived in Buenos Aires, Argentina.

Drawing on investigations in Argentine, Swiss, American, British, and Belgian government archives, as well as numerous interviews and other sources, Goñi's conclusions are detailed extensively in his book The Real Odessa: Smuggling the Nazis to Perón's Argentina (Granta Books, 2002, ISBN 1862075816), published originally in London in 2002 and since then translated into Spanish, Italian, Slovenian, Portuguese and German.

The book has had wide repercussions in those countries through which Nazi criminals and their collaborators passed in their escape, especially in Italy, Holland and Argentina.

Following publication of the book in Italy, a group of parliamentarians in Rome demanded Prime Minister Berlusconi to open an investigation into the passage of Nazis through their country.

In Milan, SS criminal Erich Priebke, sentenced to life imprisonment for his part in the Ardeatine Caves Massacre of 1944, sought a court injunction against the Italian translation of Goñi's book, demanding 50,000 euros in damages. He was turned down on both counts, despite the fact that Priebke had already won a series of judicial cases against media stories about him.

In Genoa, archbishop Tarcisio Bertone, distributed 50,000 copies of a "Special Edition" of "Settimanale Cattolico" ("Catholic Weekly") announcing the creation of a special commission of inquiry to investigate Goñi's revelations regarding the role of the Genoese curia in aiding the flight of Nazi war criminals through the port city.

In Holland, KLM opened an internal investigation following the book's unearthing of documents regarding the use of the airline by Nazi officers after the war.

In Argentina, President Nestor Kirchner ordered the repeal of a secret directive of 1938 prohibiting Argentine diplomats from granting visas to Jews fleeing from the Holocaust in Europe. This was the first official admission by the Argentine government of the anti-Semitism that marked the country's immigration policies during and after World War II. Goñi's book also caused previously secret files relating to the entry of Croatian and other war criminals to Argentina to be released.

Goñi has written for a number of British and American media, including Time magazine, The Guardian, and The Observer, as well as for various publications in Argentina.

He is also the author of two previous books in Spanish, El infiltrado, la verdadera historia de Alfredo Astiz (Sudamericana, Buenos Aires 1996), regarding crimes committed by Argentina's 1976-83 military dictatorship, and "Perón y los alemanes" (Sudamericana, Buenos Aires 1998), on wartime links between Berlin and Buenos Aires.

Uki Goñi is also a well-known musician in Argentina. He formed his first band (Space Age Serenity) while growing up in Dublin, Ireland. In Argentina he has played and recorded with major artists such as folk musician Peteco Carabajal, the rock band Mancha de Rolando, blues guitarist Claudio Gabis, pop mega-star Adrián Dárgelos as well as with his own long-time band Los Helicópteros.
