The Community Innovators Lab (CoLab) is a center for planning and development within the MIT Department of Urban Studies and Planning (DUSP). CoLab supports the development and use of knowledge from excluded communities to deepen civic engagement, improve community practice, inform policy, mobilize community assets, and generate shared wealth. We believe that community knowledge can drive powerful innovation and can help make markets an arena for supporting social justice. CoLab facilitates the interchange of knowledge and resources between MIT and community organizations. We engage students to be practitioners of this approach to community change and sustainability.
