Martha Rosler utilizes various media in her work, primarily video and photography, and also installation and sculpture; she also writes about art and culture. Her work has for decades considered matters of the public sphere and mass culture; war and geopolitical conflict; housing, urbanism, and the built environment, and systems of transportation—especially as these affect women. Many of her projects have been extrainstitutional or developed and enacted with groups of people. Rosler sees her work, her teaching, and her writing as continuations of a broader engagement with the currents of cultural critique and social and political change. Her work may best be summed up as both a conceptual art and an activist practice—focused on questions of representational form but joined, however uneasily, to a commitment to political agitation. Video, which she adopted in its infancy, presented itself as at the crossroads of both. Rosler spent the 1970s in California and Canada. In 1980, she returned to her native Brooklyn, where she lives and works.
