Ben talks with Birgit Poniatowski, the Executive Director of the International AIDS Society (IAS), about the role of professional associations in the HIV movement and IAS’s convening power. Poniatowski describes IAS’s origins in 1988, its 13,000-member multidisciplinary base including people living with HIV, and its three main conferences: the IAS Conference on HIV Science (odd years), the International AIDS Conference (even years), and HIV Research for Prevention. They discuss why the International AIDS Conference remains vital amid abrupt funding cuts and shifting donor priorities, the limits and value of hybrid/virtual formats, and plans for AIDS 2026 in Rio with the theme “Rethink, Rebuild, Rise,” emphasizing rebuilding systems for long-term realities, financing and equity, and a broad prevention toolbox. Poniatowski also outlines IAS governance changes to embed community decision-making, priorities “2026 onwards,” youth leadership programs, her career path, and how to engage via the IAS website and volunteering.
