The Broad Institute is a world-renowned biomedical research hub and is home to one of South Africa’s most prodigious youngsters in computational biology. Lindo Nkambule has been tasked with leading the development of novel software for analysing large genomic datasets, which he describes as the highlight of his career. At only 24, his best years are yet to come. Nkambule’s upward trajectory from his roots in Diepsloot and Madadeni took him to a BSc at the University of the Witwatersrand. He then qualified with first-class honours from the University of Cape Town. He also found time to kickstart Get Sum1 Out, a non-profit organisation that assists disadvantaged children with their academic performance.

I am driven to prove that indeed young people, and young black women particularly, can undoubtedly do well in these positions and beyond

The hard-won PhD in molecular medicine before her 29th birthday and her daughter’s recent graduation from grade R – these are the moments that Mpye cites as the proudest of her life. But it is more than maternal pride: having others flourish academically seems to rank alongside this research scientist’s own endeavours on her priority list. She mentors university students in her field and looks to nurture their holistic development, encouraging them to engage in extramural activities apart from their academic commitments. Offering mathematics and science tuition to high school learners is another example of this; a grassroots act of service. Her research work occupies the other end of the ambition spectrum, as she is currently involved in a project to develop test kits for rapid mycobacterium tuberculosis diagnosis. Mpye also has a penchant for travel and preaches about the wisdom one earns from wider exposure.

Follow your gut and trust your passion. Otherwise you will end up in a career that doesn’t motivate you, which will make it difficult for you to be the best version of yourself.

Pursuing a career in archaeology and travelling the world as a result have been beautiful surprises for Kelita Shadrach. She currently holds bachelor’s, honours and master’s degrees from the University of the Witwatersrand and, as a PhD candidate, her research investigates the cultural changes and behavioural adaptations of past human species. The period she studies is associated with widespread diversification in culture and represents the roots of modern human origins. Finding the courage to take on a doctoral degree is one of her proudest moments, because she had to change her internal dialogue from fear of failure to one of confidence and self-worth. “I want my parents to be able to see me graduate and I want them to be proud and know that, whilst life is often difficult and unpredictable, they raised a strong young woman who can take on science and maybe even the world.”

Making the world a better place through technology is at the core of what I do.

Ritesh Ajoodha’s expertise across diverse topics of interest is truly remarkable. A senior lecturer at the University of the Witwatersrand’s School of Computer Science and Applied Mathematics, Ajoodha combines his passion for pedagogy with his interests in music, mentorship and academic citizenship. At only 29 years old, Ajoodha has accrued degrees, diplomas and distinctions across music, education and computer science, rising through academia and actively restructuring courses and curricula. He fundraises for the National Research Foundation, has published 42 peer-reviewed articles and leads the Probabilistic Graphical Models Laboratory, where his students participate in research presentations to encourage the machine learning research community. His broad range of research topics feels disparate until you hear Ajoodha point out the common thread in his work: problem-solving. He says: “I feel strongly that if one nurtures a positive attitude and enthusiasm towards problem-solving, then one will have the potential to succeed in any domain.”

Mohube Tebeila grew up in a small village in Limpopo, far away from server banks, fibre optic cables, or any of the ideas and technologies informing her current work. Today she is a driving force in digital transformation and the application of artificial intelligence (AI) in the modern workplace in her job at Deloitte. Tebeila’s work involves helping organisations of all sizes across the globe with the implementation of modern technologies. Much of this effort involves educating management teams on how to approach the problems facing 21st century businesses. Alongside 29 other women, Tebeila is also part of the Forbes Ignite programme, which aims to leverage AI to improve healthcare services in developing regions. She attributes her success to an innate curiosity, saying: “Reading inspires a level of confidence in an individual — and the lack of that confidence can hold people back.”

I want to see the youth being inspired in being the change that they’ve always wanted to see in the world

Jade Abbott has worked as a software engineer and data scientist in every field, from fintech and non-governmental organisations to start-ups across the continent. In 2019, Abbott cofounded Masakhane, a grassroots organisation that aims to strengthen natural language processing research in African languages – for Africans, by Africans. Abbott is also a machine learning lead at software solutions company Retro Rabbit, where she is responsible for deploying machine learning systems to perform a variety of tasks for real life systems. On her aspirations, Abbot says: “I want to enable African participation to shape and own 4IR technological advances, and move us towards human dignity, wellbeing and equity.” As much as she works with technology, she has found understanding and collaborating with people far more exciting and impactful. “We are only as strong as our community, and we should maintain those relationships and reach out to them when in need.”

I’ve always been so deep into programming that I thought I’d be inventing new algorithms forever, but I’ve found understanding and collaborating with people far more exciting and impactful.

Dr Edith Phalane is a postdoctoral research fellow at the University of Johannesburg. Her current project focuses on understanding the differential impacts of Covid-19 mortality in South Africa in order to create better mitigation strategies for vulnerable populations. Phalane emphasises the importance of understanding the trends of Covid-19 deaths within the country and identifying which parts of the population have the highest risk of death. At the moment, these efforts are hampered by the scarcity of evidence and in-depth analysis on South Africa’s unique context. Phalane’s research will lead to more informed control measures and epidemiologic models that will allow a more equitable and incisive response to the pandemic. “Through my work on differential impacts of Covid-19,” she says, “I want to impact strategies and policies that mitigate the historic socioeconomic, demographic and environmental factors that serve as barriers to equal and quality healthcare services in South Africa.”

Our biggest goal is to allow Africans to create African solutions to African problems

Chemistry may have been the bane of her childhood, but with a PhD in the field, Natasha Ross can finally proclaim to have conquered her scholastic nemesis.

Artificial intelligence (AI) and data should be used to improve the healthcare sector, believes Archana Arakkal. As a thought leader in the AI and data space, her job involves providing clients in the finance sector with innovative solutions based on emerging technologies. She is also a PhD fellow at the world-renowned Massachusetts Institute of Technology and cofounder of a grassroots community initiative called SisonkeBiotik. The community of researchers, practitioners and enthusiasts aims to bridge the gap between healthcare and technology practitioners with the goal of using technology and machine learning to improve healthcare across the continent. Her ultimate goal is to see the continent-wide adoption of AI, something she believes can provide solutions for the betterment of the healthcare sector as a whole. Considering Arakkal and her team have already helped a mine reduce fatalities by 67% using AI, it’s not hard to imagine that her goal is within reach.

The greatest lesson I have ever learned is that the most powerful visionaries and pioneers take risks, and they back ideas before they are widely acceptable.
