After studying drama at St Anne's College, Katerina moved to California to study photography. Her first works were photomontages that she created inside the camera, originating from repeated exposure of a single roll of film.

In 1989 Jebb relocated to Paris and worked for the French newspaper Liberation. Unfortunately in 1991 she was involved in a car accident that paralysed her right arm. Fortunately, this only enhanced Jebb’s artistic spirit. To resolve the inability to hold a camera, Jebb began to employ machines to make life-size images, primarily self-portraits lying herself down on a high resolution scanning machine. Progressively, she diversified, posing subjects and objects, exploring the medium in parallel with the expanding possibilities in digital technology. Jebb proceeded to remove parts of the scanner to facilitate maximum extension of the subject. The resulting images, suspended and life like were embraced as a new visual medium and began to appear in Museums and Galleries, notably The Whitney Museum as part of The Warhol Look (1998), a world touring retrospective.

Jebb's work has flourished from its photographic origins, proceeding to disrupt the boundaries between mediums. Her photography has made way for video art, installations and sculpture. In her work, Jebb considers the human condition with arrant sensitivity, offering the viewer a depiction of women that rejects the normalised, commercial female role.

Her series, Simulacrum and Hyperbole (2009-2011) offers a critique of women's representation in television and advertising through parodist videos featuring renowned female icons such as Kate Moss, Kylie Minogue, Tilda Swinton, Kristin Scott Thomas and Marisa Berenson. These works simultaneously evoke laughter and pathos in their observance of the irrationality of popular expectations of women. A commission by the Balthus Fondation, was at the Metropolitan Art Museum in Tokyo in April, 2014.

Her works are included in the permanent collections of Le Musée des Arts Décoratifs du Louvre in Paris, Musée Réattu in Arles and she regularly collaborates with Olivier Saillard, Director of the Musée Galliera , and in private collections.

Jebb’s work was the subject of a solo exhibition at Musée Réattu Arles in from July 2016 - January 2017.

In 2017 her work was exposed at the Metropolitan Museum of Art in New York during the Rei Kawakubo / Comme des Garçons: Art of the In-Between. Later in the same year, she had an exposition at the Palazzo Pitti in Florence, the Ephemeral Museum of Fashion.

Dividing her time between art and commerce Jebb’s work can be seen in magazines and advertising campaigns. Alongside the world’s biggest museums and galleries, you will also find Jebb’s work in high end publications including Vogue, Life magazine, Purple and The Times and in advertising campaigns commissioned by Comme des Garçons, Louis Vuitton, Bulgari, ACNE and Hermes.
