She studied photography at the Escuela de Arte Fotográfico y Cinematográfico de Avellaneda, Argentina. In 1993 she moved to Mexico where she took workshops with renowned photographers and worked for the newspaper El Universal. In 1995 she began to work for the France Presse Agency (AFP), and was based in Chiapas from 1995-1999 to cover the armed conflict between the Mexican government and the EZLN-guerilla. In 1999 she moved to Barcelona, and in 2000 she won first prize in the FotoPres’01 contest with the project Lesbian Mothers. In 2003 she was awarded the visual arts grant from the Catalonian government for the project Visibles Spaces of Antagonism/Spaces of invisble power (Espacios visibles de antagonismo/Espacios de Poder Invisibles). In 2010 she received the visual arts grant CoNCA for the project Family-arizing.
Her work departs from defining photography as a tool for social change, focusing on exploring processes of social and political transformation and especially exploring social struggles of apparently disenfranchised groups in Latin America, Europe and Africa. In many of her projects she approaches contemporary cultural and social conditions as a narrative, the thread linking stories of struggle and resistance to the
neoliberal system that generates economic and social apartheid. She has been widely published and exhibited in many international cultural venues, and has taken part in various artist collectives and networks. (Las Agencias, Yomango, Enmedio etc.)
Oriana currently lives and works in Barcelona and is part of the artist collective Enmedio, where she initiated and coordinated the Photography in Action Workshop TAF!, which was recentely part of the art festival Steirischer herbst, in Graz, Austria.

Palais de Glace, Buenos Aires, 1992; Chiapas: rostros de la guerra, Museo Ciudad de México, 1998; Entre sueños: Primero de Mayo, Berlin Biennial, 2004.
