“When I started university, I thought I’ll go there and after three years, I will be working — only to be fascinated by the world of science, curiosity and discovery,” says Valentine Saasa.
Saasa’s research focuses on ways of diagnosing diseases using only the human breath. Early detection of lung cancer and management of diabetes mellitus without needles aren’t her only research priority: Saasa aims to apply her findings to make medical tests affordable for low-income households.
Saasa founded a nonprofit organisation called Capricorn Education Resource Centre, which helps learners from disadvantaged communities access tertiary education, aiming to help cultivate the next generation of young scientists. Sassa says her proudest moment was whern she found out that a girl she had mentored went on to study in the same field. “I’m proud that I’ve been the right representation to girls from the same rural areas as me,” she says.

“If I can do it, or if Sir Newton can do it, you can also do it. We are all human, like you.”

Zama Shabalala, a video director and the founder of Bluemag Pictures Foundation, has come to play a pioneering role in research around the medicinal and recreational potential of cannabis. With a background in both biotechnology and sales, he has spent six years working with the cannabis plant to engineer products for people with unique diagnoses.
Shabalala says that he thought he would only have an impact and realise his dreams of helping heal people if he became a medical doctor, but he is now at the forefront of the industrialisation of the hemp industry in South Africa.
Shabalala is leading a research team of students from the University of Johannesburg in studying the uses of the cannabis plant. “What drives me every morning is the passion to produce a product that will help a patient or find results that give answers to past problems,” he says.

Never stop learning. Ultimately, knowledge is the basis of creation and understanding the path one is taking.

Robert Walker is the director of Jukwaa, which manages projects such as the Sasol Solar Challenge and E-mobility Congress of South Africa.

His primary role in the company is the conceptualisation of large-scale strategic events. Through his work, he strives to become market-leading, set new standards for the sector and speed up the change towards sustainable mobility.

His proudest moment will always be the birth of his two sons, and he believes our youth have the potential to become world leaders in science, technology, engineering and mathematics (STEM). He hopes to see young South Africans “believe in a future which is clean, green and driven by STEM”.

Walker sees every day as a challenge, with his family driving him to find solutions to the seemingly impossible, but he also knows the power of learning from your mistakes. His motto is: “Don’t take failures too personally; learn from them and grow.”

“Learn to scratch the surface and not take every opportunity, no matter how good it may seem.”

A senior lecturer at the University of Johannesburg, Nomali Ngobese combines her expertise in indigenous plants with her interest in social development. She is known for her work in food security, highlighting underutilised crops to alleviate hunger and boost economic development in rural communities.

Ngobese is particularly proud of her research into proving the food potential of unconventional plants. Her studies have proven that plants such as monkey oranges and wild mangoes have nutritional value. “Having a scientific record to lobby for their commercialisation is very important, not only for the botany field, but for food processors and food engineers as well,” she says.

She addresses malnutrition in rural areas by working with potato farmers to optimise harvests. Ngobese also develops post-harvest strategies for improving the shelf life of popular crops, and creates methods to improve the nutritional profiles of popular local foods, such as steamed bread, by incorporating native plants.

“Knowing that I have a new opportunity to make a mark on the world each day drives me to excel.”

If there’s a way to make processing payments simpler, Nkanyiso Khumalo wants to find it. He’s the director of network processing and real-time payments for Visa, developing and executing processing strategies in southern Africa.

This involves working with a global technology team to design solutions fit for African markets. He also focuses on building innovative real-time payment technologies and modernising Africa’s payment infrastructure.

Khumalo has established himself as an innovator who tries to understand the root cause of a problem to find the right solution. He joined Visa’s Management Team in Southern Africa at age 29, and soon realised he had something valuable to contribute. “This led to me being bold in my submissions and to collaborate with fellow leaders around the table in resolving issues,” he says.

His aim is for everyone to have access to and confidence in making digital payments in the most effective way.

Erik Chekwube Aniogo is a postdoctoral fellow at the University of Johannesburg’s Laser Research Centre. His research interest is in cancer, cell biology, biotechnology, photobiology and photochemistry with specific reference to multidrug-resistant cancer. His research is primarily concerned with how cancer develops resistance to therapies, and in finding ways to prevent this. He’s excited about the possibility that he can “somehow use laser to excite and treat cancer cells in a new treatment modality called photodynamic therapy”.
Aniogo’s interest in translational medicine – medicine that improves human health through transferring clinical and laboratory research into medical practice – “birthed the zeal to understand why cancer recurs after treatment”, Aniogo explains. The passion for novel discovery is what fuels his ambition to be a pioneer in his research, while his specialisation in oncology was motivated by his empathetic nature to care for the underprivileged, and desire to make an impact that will benefit people affected by the disease.

“I wish to see a future South Africa where gender equity in the sciences and beyond is achieved, and where women lead in significant spaces.”

An engineer by profession with a master’s degree from the University of Cape Town, Confidence Tshilande recognised a need for a social media and networking platform exclusively for women where they could safely interact, connect, inspire and uplift one another.
As nothing of the kind existed globally, she decided to create the first. Prestiio was launched in 2021 on International Women’s Day, which Tshilande says is her proudest moment. What really sets Prestiio apart are functions such as an SOS panic button, the ability to geolocate essential services such as police stations and hospitals, and the option to engage anonymously. All its functions are intended to protect the app’s users. This ultimately realises her goal to “empower women, address the inequality gap, and improve mentorship and networking opportunities with cross-institutional partners and women’s organisations locally and globally”.

Do not give up. The world is waiting for you to unleash your potential and bring about the change you want to see.

A lecturer and researcher at the University of Johannesburg, Bonginkosi Thango’s career goal is to become the of vice-chancellor of a university.
His desire to excel is driven by the memory of his mother. A single parent, she passed away before Thango completed his matric year; she never saw her son graduate with a PhD in electrical engineering.
The diligent pursuit of his career has already seen Thango publish more than 45 peer-reviewed research papers and two international books; he’s also supervised the theses of nine postgraduate students.
With research interests in artificial intelligence, renewable energy, condition monitoring and power quality, Thango would like to contribute solutions to the various techno-economic challenges faced by South Africa in its mass adoption of renewable energy.

Anne Chisa is a PhD student at the University of KwaZulu-Natal, a science communicator and host of The Root of the Science Podcasts. The podcasts aim to amplify the voices of Africans in science, technology, engineering and mathematics (STEM) fields across the globe. “I want to shift the stereotypes that scientists are white old men in lab coats,” she says.

Through her podcasts, Chisa showcases the diversity in the field and challenges preconceptions about STEM careers. The podcasts give African scientists the opportunity to share the work they are doing, in their own voices, and to inspire people to pursue careers in STEM. She believes that sharing inspiring stories of how scientists have overcome difficulties will motivate those already in the field.

Her advice to her younger self is to believe in the validity of your vision, because “you are worthy and capable of being even greater than you imagine”.

My dream of creating a premier platform of Africans in STEM will inspire the next generation of young people to get into STEM fields.

Survivors of breast cancer, HIV or Covid-19 may have Advaita Singh to thank in the future. As an expert in biopharmaceuticals, Singh seeks natural cures for human ailments and figures out how to perfect them for commercial use. His team at the Council for Scientific and Industrial Research is producing low-cost, life-saving therapies and vaccines from plant proteins.

Singh is driven to excel by the knowledge that their work is improving the lives of ordinary South Africans. So far, one of his proudest moments was producing potent plant-based antibodies that could change the lives of HIV patients. He is often “humbled by science”, he says.

He wants to cooperate with local universities and biotechnology companies to drive South African innovation in this specialist field. This will create new openings for young scientists and biotechnologists, and make protein-based life-saving treatments more accessible to all.

“It is the small steps that add up to giant leaps.”
