Reynolds works with trajectories and ordering systems. She takes found information (for example a set of dictionary definitions or a police database) and from this she extrapolates a set of processes that result in a form being created.

Reynolds brings fugitive knowledge and connections into the immediacy of physical experience. Her work has the puzzle-like quality of something being thought through, offering an invitation to the viewer to consider the journey that has resulted in the creation of the art object on display.

Her work sometimes involves layered collaborations with institutions and disciplines outside the art context. She has worked with scientists on the Jurassic Coast in Dorset, with the Metropolitan Police, and with a group of people with dyslexia at the Serpentine Gallery. She is represented by Seventeen Gallery in London.
