I myself have already spent a third of my life in Germany, first in Cologne and then, since 1994, in Berlin.

I see the artist as a participant, a co-producer of reality.

I don't know a single collector or museum director who says: 'Oh, he's on a list, so I think I'll buy something of his.' The people who buy my art put a little more thought into it than that.

I don't think you need to be so result-oriented when you're trying to define the success of an art work. I think we can allow some unpredictability.

I always try to make work that activates the viewer to be a co-producer of our shared reality.

Photographs have a relevance for things that cannot be said.

My goal is to formulate a new color theory based on the full spectrum of visible light.
