Mackey R Friedman

  • Assistant Professor, Infectious Diseases and Microbiology
  • Assistant Professor, Behavioral and Community Health Sciences

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 the HIV Prevention and Care Project, his current work focuses on providing scientific support for multiple community-based projects promoting health among people living with, or at high risk, for HIV in Pennsylvania.

Dr. Friedman is a co-investigator on the Multicenter AIDS Cohort Study/Women's Interagency HIV Study (MWCCS) and PI of an NIH-funded R01 assessing resiliencies among aging gay and bisexual men. He is a multiple PI of an NIH-supported project to assess the psychosocial impact of COVID-19 on people living with HIV or at high risk for HIV infection; a new project assessing vaccine hesitancy in vulnerable populations; and a CDC-funded project intended to broaden pre-exposure prophylaxis (PrEP) access to local communities.

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 more than 25 years, working primarily with injection drug users, men who have sex with men, and trans people. His current extramural research efforts focus on health disparities among behaviorally bisexual males; stigma and comorbidities among aging gay and bisexual men; the evaluation of social marketing campaigns intended to reduce stigma; and the correlates of poor viral suppression in people living with HIV/AIDS. Dr. Friedman is interim Director of the Center for LGBT Health Research, and helps lead both domestic (T32) and international (Fogarty) training programs in social and behavioral HIV-related research. Dr. Friedman is Vice Chair for Practice for IDM.

Dr. Friedman teaches IDM 2019 (Emergence and Global Spread of COVID-19), offered in the Fall term.
