Katharina was born and raised in Hamburg. Her paintings focus on people – not as idealized images, but in their authenticity, with all their emotions, idiosyncrasies, and moments. The works primarily depict people from the artist's personal circle, but also scenes of unknown people from everyday life – unposed and vibrant.

The paintings don't tell grand stories – they depict small encounters, relationships, or the humor of everyday moments. Whether a fleeting moment or a personal connection within the context of a commission, the focus is always on the relationship between the viewer and the person depicted.
