Tim Horn

Deputy Executive Director  HIV and HCV Programs

A twenty-five-year survivor of HIV, Tim Horn has thus far spent his entire professional life working in the fields of HIV/AIDS treatment education and advocacy. Beginning as a writer and then editor of the Foundation for AIDS Research’s (amfAR) AIDS/HIV Treatment Directory in 1992, he also started working with TAG as an author of two advocacy-driven white papers: The Wasting Report: Current Issues in Research and Treatment of HIV-Associated Wasting and Malnutrition (1996) and The OI Report: A Critical Review of the Treatment and Prophylaxis of AIDS-Related Opportunistic Infections (1997).

Following his work at amfAR, Tim went on to complete a two-year fellowship in Mexico City, where he developed treatment education and advocacy curricula needed to streamline the scale-up of highly active antiretroviral therapy (HAART) access in Mexico’s urban and rural areas. He also completed work at the AIDS Treatment Data Network, alongside Richard Jefferys, as well as the PWA Health Group—a New York City buyers’ club.

He also spent several years as executive editor of The PRN Notebook, a quarterly journal for HIV-treating clinicians.

In 1999, he began working with TAG cofounder Peter Staley on the development of AIDSmeds.com, an online educational portal for people living with HIV and their caregivers. He became the site’s president and editor-in-chief in 2008.

As TAG’s Deputy Executive Director of HIV & HCV Programs, Tim oversees and assists in the coordination of the HIV Project and HCV/HIV Project portfolios. These include antiretroviral and direct acting antiviral (DAA) research, development, and regulatory issues; the advancement of novel biomedical prevention technologies, including antiviral drug products and vaccines; fair drug pricing and access mechanisms; and advocating for the science and policies necessary to address medical, structural, and social barriers to comprehensive HIV and HCV prevention and care services. He supervises the HCV/HIV Project Co-directors, the Basic Science, Vaccines, and Cure Director, and the Community Engagement Coordinator.

Tim and other HIV Project staff members worked in support of New York State Governor Andrew M. Cuomo’s Ending the Epidemic Task Force, which developed a statewide plan end AIDS as an epidemic in New York State by the end of 2020. This effort is part of a broader strategy by community activists, policy makers, advocates, and researchers to end the epidemic, both nationally and in key U.S. jurisdictions, by stemming new infections and ensuring that HIV-positive people receive care, are retained in active care, and remain virally suppressed. Tim was a co-author of a landmark review of the mechanisms and barriers of effective community mobilization in nine heavily affected metropolitan areas and lead author of a peer-reviewed paper conceptualizing a comprehensive primary and secondary HIV prevention continuum, both of which will serve as cornerstones of TAG’s work to strengthen and support advocacy in the years ahead.   

He lives in Asbury Park, New Jersey, with his partner of 15 years, two Boxers, a cat named Feral Fawcett, and too many tropical fish to count.
