Katrin grew up in the north of Germany. In Kiel, she studied visual arts in a mixed media class, focusing on photography, video and installation. She also studied philosophy and romance literature which led her to spend some time at the énsb-a in Paris, where she attended theory classes. Covering a wide range from aesthetics to political art, these classes encouraged her to work more in an interdisciplinary way and to explicitly refer to photo theory, psychology and philosophy.
Toine Horvers described her practice as follows: "Katrin Jaquet's work is a visual and poetic meditation about the phenomenon of photography and its inseparable relation with light, time and material".
In 2022, she published her book REVISIONS, giving an overview of her photographic works from 25 years. In the text, Nathalie Herschdorfer writes: "Rather than photography, it would be more appropriate to look at her work in terms of metaphotography".
Katrin's work has been shown in Germany and internationally.
