To meet its mandate of improving the quality of life of South Africans, the CSIR relies on its most important asset, its people. The CSIR’s multidisciplinary nature positions the organisation to help solve the increasingly complex problems of our time. This multidisciplinary science, engineering and technology base is made up of individuals who are highly specialised in their respective fields. They are geneticists, virologists, software developers, polymer chemists, applied mathematicians and industrial engineers, just to name a few.
