Prosper Chaki, PhD

Executive Director

Dr. Chaki is a Research Scientist and the Chief Executive Director for PAMCA. He received doctoral degree (PhD) in Tropical Infectious Diseases at the Liverpool School of Tropical Medicine. He spent most of his time designing and evaluating affordable community based strategies for monitoring and evaluation of programmatic malaria vector control and surveillance in both urban and rural settings across Africa. He has a broad background when it comes to working with the local communities, districts and programs supporting evidence driven decision making, intervention stratification and deployment.

In some of his past work, he investigated the influence of some specific environmental and interventional determinants to operational programs with keen interest in larval source management and in collaboration with other researchers at the Ifakara Health Institute investigated the epidemiological impact of larval control through microbial larvicide application and effective community engagement strategies for sustainable vector control interventions. He further coordinated the malaria risk mapping initiative and collaboratively helped establish the largest quality assured entomological surveillance system covering 186 villages across mainland Tanzania for evaluating the ongoing interventions and promote evidence-driven delivery of vector control programs in Tanzania.

In addition Dr Chaki is interested in innovations for accelerating malaria elimination particularly novel tools for addressing the current and emerging challenges with mosquito vector control such as outdoor biting mosquito vectors that seem to be at the centre of the malaria transmission question at the moment. He is further committed to harnessing the African based entomological capacity to spearhead capacity building for implementing vector control programs through establishing strong coordination mechanism through regional partnerships and knowledge exchange programs.

Edward Lukyamuzi

Bioinformatics Trainer (ToT) Fellow for the Anopheles Genomics Phase II project

Edward Lukyamuzi is a Bioinformatics Trainer (ToT) Fellow for the Anopheles Genomics Phase II project. As part of his responsibilities, Edward would advance PAMCA-Wellcome Sanger Institute's goal to expand bioinformatics capacity for vector genomics work in Africa. Prior to joining PAMCA, he served as a Bioinformatics Associate at the Uganda Virus Research Institute - H3ABioNet node providing bioinformatics analysis support, tool, and workflow development. His work was aimed at fostering omics analysis and contributing to the development of standard operating procedures (SOPs) for common bioinformatics data analysis tasks.  

Edward contributed to the development of an automated Next-Generation Sequencing (NGS) based pipeline for reproducible analysis of mosquito genomes, particularly for variant calling and Single Nucleotide Polymorphisms (SNP) visualization. The pipeline provides a turn-key tool to scientists in low-resource settings with the tools and ability to evaluate vector genomics data as equal partners.
