Stefan Gruber, a Carnegie Mellon University professor of architecture and urbanism, sees cities as a prime site of struggle between capitalism and commons, and therefore an important incubator of just, regenerative, self-determined communities that move beyond the market/state paradigm. The traveling international exhibit, 'An Atlas of Commoning,' which he helped curate, and his course on 'Commoning in the City', study how participatory action, community design, and creative commons/public partnerships are reinventing urban life.
