In this issue of e-SPAN, we honor the work of Valentina Vavasis, Sarah Rafson and Steve Lee, three beloved faculty members. We speak with Valentina, whose expertise in real estate, community development and professional ethics is braided together with her deep care for—and curiosity about—humans and human community. Sarah reflects on her years as Carnegie Mellon Architecture’s Curator of Public Programs, and the inquiry they’ve opened and the conversations they’ve inspired. And we highlight Steve, alumnus, professor and former Head of School, who is retiring after 43 years with the school.
