معرفی
Helen Ayles is a Professor at the London School of Hygiene & Tropical Medicine with extensive experience in HIV/TB epidemiology and public health interventions in sub-Saharan Africa. She has served as a principal investigator for major research initiatives including the HPTN 071 (PopART) trial, a large community-randomized study examining universal HIV testing and treatment in Zambia and South Africa.
Her research interests span HIV prevention and treatment strategies, tuberculosis control, community-based health interventions, HIV/TB co-infection dynamics, and neglected tropical diseases such as schistosomiasis. Recent work has expanded into adolescent sexual and reproductive health, menstrual hygiene, and pandemic response in resource-limited settings. Her methodological expertise includes epidemiological modeling, cluster-randomized trial design, and implementation science.
Analysis of her recent publications (2024-2025) reveals a strong focus on HIV/TB co-epidemics, with significant contributions to understanding transmission dynamics through sexual networks, improving diagnostic approaches for TB, and developing community-based interventions for HIV testing and treatment. Her work increasingly addresses gender-specific health challenges, particularly regarding adolescent girls and young women's health in Zambia.
Dr. Ayles has led or contributed to numerous international collaborations including the BILGENSA Research Network focused on genital schistosomiasis in Southern Africa, and has been instrumental in designing and evaluating large-scale public health interventions across multiple African countries, particularly Zambia.
Her research has directly informed public health policy through evidence on universal testing and treatment strategies, community-based ART delivery models, and approaches to reducing HIV stigma in high-burden settings. She has mentored numerous researchers working across the HIV/TB spectrum and continues to lead cutting-edge research addressing some of Africa's most pressing public health challenges.
