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 in Paris, where she attended theory classes at the énsb-a. 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. After experiments in which she confronted photographed images via light projection with real matter, like human bodies and faces, she started looking at photography in a more philosophical way".
