Peter has had one of his photographs added to the permanent collection of the Worcester Art Museum. Since he started teaching at Trinity in 2002, the Princeton Art Museum, Wesleyan University, and the Yale University Art Gallery have acquired photographs from his Warm Roomseries. He has appreciated all the institutional support that has helped in this effort.

Peter Moriarty published introductory notes about work by fellow Visual Arts Department teachers Bruce Edelstein and Thomas Holton that is showing at Hillwood Art Museum at the C.W. Post campus of Long Island University from 12 September - 5 November 2011.

Peter, with the help of a Trinity School Parent Association grant, spent six weeks, from 3 July 2010 to 16 August 2010, photographing significant British and European glass houses. These photographs are added to his American portfolio of orangeries. Peter filled twenty-eight rolls of film at such places as Kew Gardens and Chiswick House in London; Chatsworth House in Derbyshire, England; the National Botanic Garden of Belgium; Strasbourg, France; the Jardin botanique de Nancy, France; and the greenhouse in the Paris Museum of Natural History.

He is currently editing the work and looking for a suitable venue to exhibit the photographs.

Peter was asked to define a critical context for looking at the current show, Bluebird, by the Italian photographer, Frank Dituri, which is at Long Island University’s Hillwood Art Museum.

Peter gave a lecture on photographer Danny Lyon at the Hillwood Art Museum at Long Island University on 22 October 2009. The museum exhibited Lyon’s series “The Bikeriders,” 1960s photographs of the infamous Chicago Outlaws Motorcycle Club.
