The National Institute for Theoretical and Computational Sciences is a South African institute working across eight core disciplines: astronomy and astrophysics, bioinformatics and quantitative biology, data science, earth systems and climate change modelling, mathematics, quantitative finance, statistics and theoretical physics. Its student pipeline combines DSTI-NRF-funded bursaries with internship and mentorship programmes for undergraduate and secondary students, summer schools in coding and mathematics, mini-schools and colloquia, and software and data carpentry training courses. Programmes are open across South African institutions rather than tied to a single campus, and the institute also signposts external funding routes for graduate study.
