Dr. Prosper Chaki served as a Chief Research Scientist at the Ifakara Health Institute and previously held the position of Chief Executive Director of the Pan-African Mosquito Control Association (PAMCA). He obtained his doctoral degree in Tropical Infectious Diseases from the Liverpool School of Tropical Medicine.

His professional work centred on the development and assessment of cost-effective, community-driven approaches for malaria vector control monitoring and surveillance, implemented across diverse urban and rural contexts in Africa. Dr. Chaki worked closely with community members, district authorities, and national programmes to strengthen the use of scientific evidence in planning, targeting, and implementing malaria control interventions.

Dr. Chaki’s research explored how environmental factors and control measures influence malaria transmission, with particular emphasis on larval source management. Together with colleagues at IHI, he contributed to studies evaluating the impact of microbial larvicides and community participation on the sustainability and effectiveness of vector control efforts.

He played a leading role in coordinating malaria risk-mapping initiatives and was instrumental in the establishment of a large-scale, quality-assured entomological surveillance network spanning 186 villages across mainland Tanzania. This system has been central to assessing ongoing interventions and supporting evidence-based delivery of vector control programmes nationwide.

In addition, Dr. Chaki was deeply engaged in advancing innovative solutions to support malaria elimination, particularly in response to emerging challenges such as outdoor-biting mosquito vectors. He was strongly committed to building and strengthening African entomological expertise through regional collaboration, institutional partnerships, and structured knowledge-exchange platforms.
