I am a freelance artist since 1983. Initially, paintings and drawings on classical substrates. In addition, black and white photographs.

From 1987 I turned increasingly to unconventional materials and techniques. The first pictures were created on acrylic glass and foils – painting surfaces, which I now devote myself exclusively. At the same time I made three-dimensional object subjects from found materials.

In 1978, during my studies in Hamburg (Illustration and Communication Design), I founded the poster group „*WERKHAUS*“ with a small group of graphic and art students.

In 1981, I conceived the slogan „Imagine it’s war and no one is going“ as a wall slogan. The photo of my graffiti on the wall of the bunker on the Heiligengeistfeld as well as my poster with the wall graphic went viral and made the slogan known beyond the borders of Germany.

In addition to my artistic work, I designed book covers and posters, worked in the 90s full-time as an art director and part-time as a depth psychological body therapist. After the turn of the millennium I worked as a web designer.

From 2003 I realized smaller solo exhibition projects in my own exhibition space in Hamburg. After a good course of a serious illness, I am since 2019 again working full-time as a freelance artist.
