Teaching diverse groups of students in the U.S., Brazil, and Italy has shaped my sensitivity to the uniqueness of each place’s diversity. I envision teaching the spatial aspects of spatial justice to foster design as a collective practice of designer-citizens committed to improving the human condition. On the one hand, I lead students to connect overarching patterns of inequality to situated practices that sustain them. On the other hand, I leverage my position inside and outside academia to encourage them to turn problems into opportunities for social change by collectively re-imagining them as more sustainable and just.
