Early life and education
editMasimirembwa was born in 1967 in Zimbabwe[5] and received his BSc (Hons) and DPhil degrees in Biochemistry from the University of Zimbabwe in 1993.[6] Fascinated by the then-emerging field of pharmacogenetics, he conducted studies at the Karolinska Institute in Sweden in 1995,[5] where he earned his PhD in Medical Biochemistry and Biophysics. His doctoral research was centered on the molecular mechanisms of drug metabolism and toxicity.[7][8]
Career and research
editAfter obtaining his PhD, Masimirembwa returned to the University of Zimbabwe and served as a Senior Lecturer and Head of the Department of Biochemistry from 1992 to 1997.[6] He later joined AstraZeneca R&D in Sweden as a Principal Scientist and Project Leader, focusing on drug discovery and development in various areas such as cardiovascular, gastrointestinal, and infectious diseases. He played a key role in establishing the AstraZeneca Africa Pharmacogenetics Research Network, which aimed to study the genetic diversity and drug response of African populations.[7][6]
Later in 2008, Masimirembwa founded and assumed the position of President and Chief Scientific Officer at the African Institute of Biomedical Science and Technology (AiBST), a non-profit research institute in Zimbabwe that focuses on biomedical science and technology, with an emphasis on pharmacogenetics and clinical pharmacology. [9]
At the institute, he manages collaborations with various academic, industry, and government partners. He also leads the African Pharmacogenomics Consortium (APC), a network that aims to advance pharmacogenomics research and applications in Africa.[6] He is also a Distinguished Professor of Health Sciences Research at the University of the Witwatersrand (South Africa). [7][10]
Masimirembwa is a fellow of the Zimbabwe Academy of Sciences (ZAS)[5] and the African Academy of Sciences (AAS) among many other honors. In November 2021, Masimirembwa was selected as a Calestous Juma Science Leadership Fellow by the Bill and Melinda Gates Foundation, to develop a research and innovation ecosystem, train scientists, and create centres of excellence in genomic medicine research to enhance Africa’s sustainable development in genomic and pharmaceutical capabilities.[11]
