When São Paulo, Brazil, gifted an empty 12,000 square foot building to the city's homeless, a world of opportunities and needs was created. Susan Melsop, an associate professor in the Ohio State Department of Design, had recently received the Ronald and Deborah Ratner Distinguished Teaching Award, which gave her the opportunity to create a social impact design project abroad. Over the course of several months, she developed academic and NGO partnerships in Brazil and formed a design class to illustrate how design can be an agent for change and social justice. More about her experience is available on this week's Voices of Excellence
