She started her professional career at the end of the 80's as well. Her work appears as photographs, installations, objects and video. In her work she questions the human existence, cultural taboos bounding with the body, the conventions, the stereotypes and the behavior.
At the beginning of his professional career at the end of the 80's he concentrated on addressing the problems of recognizable visual signs and their interaction with meanings and codes. Later on, his interest for spatial visual constructions was reinforced and he dedicated himself mainly to installations, operating with a language close to minimalism, involving the visual mediation of video, camera obscura, mirror reflections and spatial lighting effects. The artist usually drives his spectators to recognize almost physically alienation and loneliness, pressing them to ask basic questions about existence in the contemporary world which is frequently perplexed by fictive communication.
