The research focus of the Chair in M3B2 lies at the intersection of mathematical modelling of biological processes and a spectrum of mathematical specialisations, broadly located within analysis. The biological processes to be considered within the Chair are highly relevant to the needs of the country. These include mathematical epidemiology, specifically the identification of adequate scientific, engineering or medical responses to new diseases and old forms of new diseases, such as covid-19, malaria, tuberculosis, cancer, HIV/AIDS and other communicable diseases that pose a massive threat to development in South Africa and beyond. The Chair also develops new mathematical and numerical methods for broadly understood population dynamics, ecology and other fields of interest in life sciences.
