Guy was born in Italy in 1978. He spent his childhood between Italy and the US. In 1997 he moved to Milan, where he studied and worked until late 2003. He received a degree in Communication Science from an Italian university in November 2003 upon the completion of a thesis project focusing on the semiotics of Vietnam War photography. In early 2002 he completed a professional photography course in Milan.

Since 2003 Guy’s work has been focused on conflicts and social issues, mainly in the Middle East and Africa. He moved to Ethiopia’s capital, Addis Ababa, in 2006 to concentrate on contemporary African issues while working for his editorial clients. Guy is deeply committed to exploring the continent’s social dynamics at every level, from small sub cultures in its mega capitals to the changing lives of rural communities whose social structures have been so dramatically altered in the last century.

Several of the publications that have featured Guy’s photography include: Vanity Fair IT, US and DE, L’Espresso, Le Figaro Magazine, Paris Match, National Geographic, Le Point, GQ Italy, Der Spiegel, US News & World Report, Newsweek, USA TODAY, Specchio, Max De, The New York Times, Time Magazine, D, Cicero and Stern.
