Joanna Rajkowska is a versatile artist, but her best-known works are public projects. To build them, the artist uses real existing places, energies, organisms and materials. In doing so, she uses elements as diverse as plants, buildings, found objects, water, smoke and sound. The results of her work range from urban axes and architectural designs to geological fantasies, archaeological digs and underwater sculptures. Most of her works are created, live and age in open space, so their matter is not only the matter of all entities, organic and inorganic, included in them, but also their complex relationships.
Rajkowska produces films, photographs and models within and outside of public projects.

De-taming, de-humanizing and building relationships are the methods the artist uses most often. Her goal is to reduce human activity, multiply causal entities and human and non-human relationships. The artist treats her projects like organisms, focusing on the life of matter in its molecular dimension, life cycles, growth and aging. Convinced that humans, as a species, have not been able to create a vital, sustainable culture, the artist often juxtaposes (human) historical and sociopolitical contexts with the lives of other species. Her work visualizes and questions the dichotomy of the separation of nature and culture, which is often combined with a strongly felt note of disillusionment.
