Peter O. Muller is Professor of Geography at the University of Miami. Dr. Muller is a nationally recognized expert on suburbanization in the U.S. His primary research interest involves the changing geography of employment within large U.S. metropolitan areas. Jobs are steadily suburbanizing as cities continue their restructuring. It is commonly believed that employment is heavily concentrating in suburban downtowns or "edge cities" but the evidence he has gathered so far suggests that the dispersion of commercial-office-based activity is the more important force. He therefore hypothesizes the presence of "edgeless cities." This may indicate that suburban sprawl may be as pervasive for nonresidential activities as it is for residential decentralization.
