Her idea of design is influenced by her training at the studio belonging to Ettore Sottsass in Milan, and by the contamination of both her Turkish culture and the Italian culture. She is a partner of Studio Koz-Susani Design, headquartered in Chicago.

Her work ranges from designing household objects to technological devices, from luxury craftsmanship to mass-production products, with a particular focus on the sensory quality of materials. Her lamp, Circus, combines blown glass with metal in a single, simple and harmonious shape.
