Drawing upon aspects of photography, assemblage and text, Koch's work calls attention to often unremarked upon elements of everyday life.

Over the years, his work has been shown in garages, on kiosks and billboards, as well as museums and galleries in New York, London, Brussels, Seoul, Toronto, Chicago and Los Angeles and elsewhere, and is in permanent collections internationally, including the Metropolitan Museum, Maison Européenne de la Photographie-Paris, Staatsgalerie Stuttgart, Whitney Museum of American Art, Museum of Contemporary Art-Chicago, and San Francisco Museum of Modern Art.

"When Things Dream," the third installation of Koch's Garage Trilogy can be viewed as a virtual tour at www.afsnitp.dk/galleri/garageography/ (allow 20 sec to load).

As an artist-in-residence at Copenhagen's Fotografisk Center, an earlier web project, "Touchless Automatic Wonder," was the precedent for his recently released book (2009, Borderland Books/ UW Press) by the same title.
