From the mid-1980s to the mid-1990s he was an essential member of the Cologne art scene, as evidenced by his exhibitions in Cologne, Maastricht, Asperen, Aachen, Hamburg, Wuppertal and Mannheim. Collaborations with prominent German contemporaries are an essential part of his work. Long-standing friendships with Martin Kippenberger, Walter Dahn and others were the basis for joint exhibitions.
