Lori Heise is Founder and Co-Director of the Prevention Collaborative, an international NGO that works with local partners to end violence against women and children by improving prevention practice, fostering innovation and strengthening the global prevention ecosystem. She is an internationally recognized expert on the causes and consequences of intimate partner violence and on effective strategies to prevent it. Early in her career she founded and led two women’s health organizations—one dedicated to sexual and reproductive health and a second focused on women’s HIV prevention needs. Between 2010 and 2020 she worked as a Professor at the London School of Hygiene and Tropical Medicine and the John Hopkins Bloomberg School of Public Health, where her research focused on conducting rigorous evaluations of strategies to reduce gender based violence and to address the upstream structural drivers of HIV, including gender inequality, insecure livelihoods, alcohol and drinking norms, transactional sex, and stigma and criminalization.
