Personal Statement

Dr. Friedman joined the University of Pittsburgh's HIV Prevention and Care Project in the Department of Infectious Diseases and Microbiology (IDM) in November 2005.  As Principal Investigator of Project Silk, his current work focuses on designing, implementing, and evaluating a CDC-funded HIV prevention demonstration project with young Black men who have sex with men and transgender individuals.  A native of Chicago, Dr. Friedman received his BA (English) from the University of Minnesota and his MPH (Infectious Diseases and Microbiology), Certificate (LGBT Health and Wellness), and PhD (Behavioral and Community Health Sciences) from the University of Pittsburgh Graduate School of Public Health. He has worked in HIV prevention for the last 20 years, working primarily with injection drug users, sex workers, men who have sex with men, and homeless and runaway youth.

 His current extramural research efforts focus on health disparities among behaviorally bisexual males; the context of male and transgender sex work in urban settings in the United States and developing world settings; and the evaluation of social marketing campaigns intended to reduce stigma.  He is collaborating with the Pennsylvania Department of Health and NASTAD to help diffuse the Project Silk model regionally and nationally.
