Born in Jerusalem, Sigalit Landau studied at the Bezalel Academy of Arts and Design in Jerusalem and the Cooper Union School of Art in New York. She gained international prominence for her site-specific installations and performance-based works that often engage with the landscape and history of Israel.

Her practice spans drawing, sculpture, and video, with a signature focus on the transformative effects of the Dead Sea's salt on submerged objects. This process results in crystalline, sculptural forms that serve as both physical artifacts and metaphors for memory and environmental change.

Landau continues to maintain a significant presence in the global contemporary art circuit. Her work is held in the permanent collections of major institutions such as the Museum of Modern Art in New York and the Centre Pompidou in Paris, and she remains an active participant in international gallery exhibitions.
