With more than 10 years of experience in teaching, research, and community engagement, Dr. Bayiga’s work focuses primarily on non-communicable diseases, especially trauma, injury, and disability. She has developed strong expertise in road safety research, examining the influence of the built environment on pedestrian safety, the effectiveness of road safety interventions, and the quality of pre-hospital and emergency care for road traffic crash victims. She has published more than 10 scientific papers in this field under the name Esther Bayiga-Zziwa. Her broader research experience includes contributing to WHO-AFRO analyses of the population health workforce in Africa, particularly its alignment with disease burden trends using epidemiologic methods. She has also undertaken work on costs and cost drivers of health interventions, knowledge translation, and, more recently, the politics of urban mobility. She is currently a Co-Principal Investigator on an NIHR-funded project, Politics of Urban Mobility in African Cities (PUMA), comparing urban mobility systems in Kampala (Uganda), Kigali (Rwanda), and Lilongwe (Malawi). Dr. Bayiga serves on the WHO Expert Advisory Group on Powered Two- and Three-Wheeler Safety, contributing to global efforts to reduce the burden of road traffic crashes. She has supervised both undergraduate and postgraduate students across a range of methodological and thematic research areas.
