Sigrid Sandström primarily works with painting, and in her artistic practice, she continuously explores place as a concept as well as an emotional experience. Over time, the often depicted large-scale, barren, and uninhabited landscapes have become more abstract. Her works cannot be categorised but instead continuously investigate the conditions and limitations of painting. A painting's fundamental elements are colour applied to a physical surface, but within these parameters, there are countless possibilities for variation.

Throughout her career, Sandström has chosen painting as her medium of expression, while constantly pushing the boundaries of its traditions. She aims to make us see her paintings not just as images, but as physical objects to be experienced. Her craftsmanship is experimental, employing techniques such as masking, printing, and pouring methods, and the time during which a work emerges seems almost encapsulated in the many layers.

Sandström is one of her generation's most established artists, with a number of major exhibitions in both the USA and Sweden behind her. She is also a dedicated professor of fine arts with a focus on painting, previously at the Royal Institute of Art in Stockholm and now at the Academy of Fine Arts in Helsinki. Sandström studied at Yale University School of Art, graduating in 2001.
