Diab addresses the contradictions and obstacles of political conflict, globalisation, and exile through playful symbolism, references to popular culture, iconic imagery, and narrative structures. With each new series he adopts a different painting style, reflecting the impermanent nature of art as it becomes increasingly conceptual and further dematerialized.

Born in 1977 in Damascus, Oussama Diab is a Palestinian - Syrian contemporary artist who lives and works in Netherlands. He graduated from the Faculty of Fine Arts in Damascus in 2002. Diab has worked through various painting styles, often combining different forms and techniques in a single composition.

He describes his work often as autobiographical. Signs of dislocation, confusion, are woven among historical citations, icones and references to popular culture. Traces of war, revolution and migration are represented in his canvases. The artist sets his characters against decorative and ornamental backgrounds that seem to extend out of his canvas with no beginning and no end. Although Diab's figurations attain a level of elegance and grace, they possess intense melancholy.
