Rosenau joined the University of Southern California in 1973 and served as director of the School of International Relations there from 1976 to 1979. In 1992, he was appointed professor of international relations at George Washington University. He served as a professor of international relations at the university’s Elliott School of International Affairs until his death in 2011. In 2005, he was included on a list of “the most influential scholars in the field of international relations” published by *Foreign Policy* magazine.
