Mmaki conducts education technology research focused on increasing STEM education across the African continent through mobile technology. As one of the first black, female South Africans to complete a PhD in Computer Science, Mmaki strives to make STEM education more readily available to others. She’s created a digital application that allows children to translate STEM instruction from English into their local language. The app is currently being used in eight schools across three districts and she hopes to expand. Mmaki further founded a non-profit organization Peo Ya Phetogo which supports underprivileged schools with digital skills training programs for teachers and learners.
