Professor David Lyon is the Queen's Research Chair in Surveillance Studies at Queen's University in Canada. He is a sociologist with research interests in surveillance and social sorting, identification regimes, citizenship, privacy, information technologies, religion and postmodernity. Lyon has written the modern day classic books on surveillance and has been integral in building the "surveillance studies" research domain. Below is a video of Lyon speaking on social sorting.
A quick search on Amazon.com can provide at least a start into the influential texts that Lyon has written and edited. See especially Surveillance as Social Sorting: Privacy, Risk and Automated Discrimination (2002); and Electronic Eye: The Rise of Surveillance Society (1994).
Lyon has been pivotal in establishing the New Transparency Research Project.
