Jeffrey is an urban ethnographer who writes about the ways in which mediated communication and community come together in the life of the inner city. His research integrates face-to-face and digital fieldwork to understand how interpersonal relations and ties between people and institutions unfold over time. The Digital Street is the title and subject of his forthcoming book with Oxford University Press on the networked communication that brokers street life. Jeffrey is a Junior Fellow of the Yale Urban Ethnography Project. At Rutgers, he teaches courses on mediated communication.
