BIO
Sam Friedman has worked on research concerning people who use drugs and HIV since 1983. During this time, he has written widely on related epidemiology and prevention topics. His work has contributed substantially to what we know about drug users’ social networks and their relations to HIV epidemics; to our understanding of macro-social epidemiology of drug use and its associated diseases; to the theory and practice of drug users’ organizations and their efforts to reduce the spread of HIV and other infections among them; to efforts to prevent HIV transmission by drug users and others who have recently become infected; and to our understanding of how HIV and other epidemics among people who used drugs do or do not spread to non-users in their communities.
