Gregg Gonsalves is a leading figure in global health whose career bridges hard science and unapologetic activism. Trained as an epidemiologist and now a professor at Yale, he first came to prominence during the HIV/AIDS crisis as a member of ACT UP, where he helped force governments, regulators, and pharmaceutical companies to respond to the epidemic with urgency and evidence-based policy. That activist grounding has shaped his academic work ever since.
Openly gay, Gonsalves has been clear that his experience of the AIDS crisis is not incidental to his scholarship. It sharpened his understanding of how stigma, inequality, and political failure can drive disease as much as biology does. His research and public commentary span HIV, tuberculosis, COVID-19, and global health security, consistently emphasising equity, accountability, and the real-world consequences of policy decisions.
Gonsalves is also a prominent public intellectual, known for calling out misinformation, complacency, and institutional cowardice, even when it is uncomfortable. He exemplifies a model of science that does not retreat from politics but engages it directly, insisting that rigorous evidence and moral clarity belong together. In doing so, he has helped redefine what it means to be both a scientist and an activist in public health.
