Simon Gregson

Professor Simon Gregson serves as Professor in Demography and Behavioural Science at the School of Public Health, Faculty of Medicine, Imperial College London, and directs the Manicaland HIV/STD Prevention Project in Zimbabwe. His work focuses on HIV epidemic dynamics across sub-Saharan Africa through integrated empirical and modeling approaches.

Gregson specializes in HIV transmission dynamics, prevention strategies, and epidemic impact assessment using longitudinal population-based surveys combined with mathematical modeling. His landmark 19-year Manicaland study in Zimbabwe provides critical evidence on HIV decline drivers, influencing global public health policy. Research spans demographic methods, infectious disease epidemiology, and behavioral science applications in resource-limited settings.

As Director of the Manicaland HIV/STD Prevention Project, Gregson oversees sustained research funding for longitudinal epidemic tracking, involving multi-institutional collaborations across Zimbabwe and international partners. His leadership coordinates field operations, data collection, and analytical teams generating policy-relevant evidence.

The Manicaland project team conducts population-based surveys and clinical studies across 12 communities in eastern Zimbabwe, maintaining one of Africa's longest-running HIV surveillance systems. This infrastructure enables real-time monitoring of epidemic trends and intervention impacts through household visits, biological sampling, and behavioral interviews.
