President Lee C. Bollinger created the Arts Initiative at Columbia University in 2004 to change the role of the arts across the university, and hired Mosher as its first director, a position he stepped down from in Fall 2010. Since its inception the Initiative has developed programs to enliven the arts on campus and to link the university's intellectual mission to New York's cultural life. Among its programs are Passport to NYC, which provides Columbia students with free admission at 28 New York City museums, including the Metropolitan Museum, MoMA and the Guggenheim.
