Yuval is a graduate of the Philosophy department at Tel Aviv University, the Curating Contemporary Art Programme at the Royal College of Art, and a scholar of the Kenneth Lindsay award, AIA. His main areas of research are: appropriation of found photographic materials, collage, and the application of linguistic theories in the study of visual culture and art.
In his current research project at the Ruskin School of Art Yuval focuses on the semiotics of image appropriation mainly through the case study of British artist John Stezaker's body of work. Stezaker's self made archive of found photographic materials, postcards, and film-stills is at the origin of his prolific photo-collage based practice, which according to Etgar, lends itself to a theory of visual syntactical play. Both Etgar's writing and his curatorial practice examine the way metaphors, alongside other semantic tropes, such as catachresis, metonymy, and synecdoche, contribute to a study of the 'use' and 'appropriation' of found photographic materials in modern and contemporary art.
