At the heart of Collishaw's practice is an exploration of the uncanny. Drawing inspiration from Victorian symbolism, art history, natural science, religion, and emerging technologies, he creates works that appear beautiful at first glance before revealing unsettling narratives beneath their surface. Butterflies, flowers, birds, anatomical studies, and historical imagery recur throughout his work, becoming vehicles through which he examines themes of mortality, desire, illusion, and human vulnerability. By juxtaposing exquisite craftsmanship with psychologically charged subject matter, Collishaw creates artworks that are simultaneously alluring and deeply unsettling.

Collishaw is perhaps best known for his ability to merge traditional artistic references with cutting-edge technology. Throughout his career he has embraced photography, film, virtual reality, kinetic sculpture, and digital animation alongside more traditional printmaking and sculptural techniques. Works such as Thresholds, The Mask of Youth, and his celebrated Insecticide series demonstrate his fascination with perception, transformation, and the tension between creation and destruction. This innovative approach has established him as one of Britain's leading interdisciplinary contemporary artists.

His work has been exhibited extensively at major museums and institutions worldwide, including Tate Britain, the Victoria and Albert Museum, Somerset House, Kew Gardens, the Bass Museum of Art, the National Science and Media Museum, and the Centre Pompidou. Collishaw has also represented Britain in numerous international exhibitions and biennials, while his works are held in prestigious public collections including Tate, the San Francisco Museum of Modern Art, the National Galleries of Scotland, the Museum of Contemporary Art San Diego, and the Irish Museum of Modern Art, among many others.

From an investment perspective, Mat Collishaw occupies a highly regarded position within the contemporary art market.
