Saidi Kapiga is a clinical epidemiologist who has been working at London School of Hygiene & Tropical Medicine since 2007. Before coming to the School, he was an Associate Professor of reproductive health at Harvard School of Public Health, MA, USA. Saidi is currently based fulltime in Mwanza, Tanzania where he is the Scientific Director of the Mwanza Intervention Trials Unit (MITU), the Unit established by the School in partnership with the Tanzanian National Institute for Medical Research (NIMR). MITU’s mission is to contribute to improving health through the development and evaluation of interventions against HIV and other health problems. It seeks to achieve this by conducting research, including clinical trials, to the highest international standards; to enhance the capacity to carry out such research in Tanzania and the East African region; and to contribute to the translation of research findings into health policy in partnership with other stakeholders. Saidi is a member of several research and capacity development programmes in East Africa, including the Wellcome Trust funded THRiVE to Research Excellence consortium, and the Lake Victoria Consortium for Health Research that aims to improve the health of populations in fishing communities in Kenya, Tanzania and Uganda.

Saidi is currently involved in teaching students undertaking distance learning courses in epidemiology, public health, infectious diseases and clinical trials.




Saidi Kapiga’s main research interests are in the epidemiology and control of HIV and other sexually transmitted infections (STIs). For more than 28 years, he has conducted studies to investigate the biological and behavioural risk factors for HIV/STIs and other sexual health problems, and examined the impact of preventive interventions in a range of populations, including adolescents and young people, and among women at increased risk of HIV. He is particularly interested in the development of female-controlled HIV prevention methods, including microbicide products containing antiretroviral drugs; epidemiology of alcohol use and alcohol use disorders; impact of alcohol interventions on a range of health outcomes, including HIV transmission and treatment outcomes in people living with HIV/AIDS; and the associations between HIV and other chronic conditions.


More recently, Saidi expanded his research interests to include non-communicable diseases (NCDs), health systems, and intimate partner violence. He is a Co-PI of a study to describe the epidemiology of NCDs and investigate strategies to improve the effectiveness of health services in controlling NCDs in Tanzania and Uganda; and a trial to assess the impact of gender training intervention on reducing physical and/or sexual intimate partner violence. He is also involved in studies to determine environmental and genetic determinants of type 2 diabetes in sub-Saharan Africa; the incidence of high blood pressure among adolescents and young people; and the incidence of hypertension among HIV patients using antiretroviral drugs.
