MILLA-KARIINA OJA left Finland at the age of 19 and studied photography art at Manchester Metropolitan University from 1996 to 1999. While working towards her BA degree she went to Spain as an exchange student to study at the University of Castilla- La Mancha in Cuenca. After graduating from Manchester she moved to Spain where she continued her studies in a Ph.D. program at the University of Barcelona in the faculty of fine art.
 
In 2003, Oja had her first solo exhibition in a prominent gallery, Galeria Ferran Cano, in Barcelona. Since then, her works have been exhibited in galleries, photography art centers and museums in Europe. Her previous solo exhibition, Cat's Cradle, was shown in China for the first time at the Lianzhou International Photography festival in 2006. The same work was later exhibited in Beijing at the Zenith Gallery in a show together with Chinese photographer Jiang Pengyi.
