At PennDesign, Guerra studies how land use, development and technology intersect with transportation. He also currently serves as the director of education and outreach for Mobility21, a federally-funded initiative led by Carnegie Mellon University that brings together researchers from various disciplines to improve transportation systems, safety and efficiency.

Guerra describes city planning as a “generalist” field, though he finds himself becoming increasingly specialized in his own research. “We work across a broad range of subjects,” he says. “I like the focus on design, on history, on social movements and social work.”
