With a PhD in physics in his pocket, Dr Amos Kiyumbi plans to invest his research experience in Germany and South Africa into the establishment of a photonics initiative in Tanzania. For his PhD research, Kiyumbi developed a proof-of-concept optical biosensor for the detection of low levels of the malaria parasite in blood samples. His research paves the way for the development of biosensors to support future vaccination efforts in low-resource areas.
