As a designer and art director for film producers, concert promoters, museums, theatres and publishers, he combines unconventional ideas with practical Swiss tradition. His clients include international corporations such as Swissair, Nikon and IBM as well as smaller firms, publishing houses and institutions.

The content being conveyed and the visualization of the message are paramount to his work. To achieve this, he chooses the technique that can be used best to interpret the content, be it typography, drawing, painting or photography.

He returned to working by himself in his studio since 2015.

He has taught at several universities, held lectures and workshops around the world and was a professor at Bern University of the Arts (1999–2014).
