Katy's practice is about the human body, specifically the internal anatomy. The intention is to abstract the abject and unseen into the opulent and beautiful. The translation intentionally retains an edge of the horrific to prevent complete loss of the repellent and thereby trespassing into the saccharine.

The research for her work involves observational drawings and photography of surgeons at work in the operating theatre. The use of precise drawing is retained in the paintings, and this cross references the history of anatomical drawing.

On top of the drawing a variety of materials are used such as spray paint, enamel, paper and fabric which she has embroidered. She then sews directly into the canvas. The paints are rubbed back and repeated to create obvious and hidden marks. This reflects the different matter within the internal body. The use of stitch is particularly important to the work, invoking the repair of the patient.

5cm deep canvas presents the painting as a three dimensional object which alludes to the presence of the body. The use of a canvas observes the language of fine art and removes possible associations of collage and stitch with craft.

Her work is held in public and private collections, including the V&A.
