I teach and research on urban studies and planning. My interests are global, but primarily concentrated in the Americas. I have lived and worked nine years in Latin America, and I have ongoing projects in Peru, the Bronx, and the Capital Region. I have done a lot of work on urban micro-enterprises, particularly street and market vendors. I am also strongly interested in: urban poverty and popular culture; the dynamics of neighborhood change; the impact of immigration on major cities; metropolitan growth and management strategies; and, the history of urban, regional and national planning. My research is primarily qualitative, using the methods of ethnography, journalism and local history. My most recent publications are:
