Chemical Engineer Turns Curiosity into Solutions for Cleaner Future
International student, Mr Jonathan Byamungu’s graduation with his MScEng is spurring him on to further study.Chemical Engineer Mr Jonathan Byamungu graduated with a Master of Science (MSc) in Engineering from the University of KwaZulu-Natal (UKZN).
Supervised by Professor David Lokhat, Byamungu, who is an international student from the Democratic Republic of the Congo, completed both his undergraduate and postgraduate Engineering degrees at UKZN, saying his positive early academic experiences played a decisive role in his decision to study further at the Institution.
“What motivated me to do my MSc through UKZN was the experience I had during my undergraduate years,” Byamungu explained. “I had the opportunity at an early stage to interact with some of the projects Professor Lokhat was conducting with the then Reactor Technology Research Group, on how to extract valuable metals from electric waste.’’
“This experience allowed me to start thinking more about how I could use my acquired engineering skills to explore this concept of waste valorisation for environmental remediation further,” he said. “It pushed me to apply this thinking to different problems, including what eventually became my MSc research topic.”
For his master’s research, titled ‘Desulphurization of Bioethanol Using Copper-loaded Carbon Foam’, Byamungu investigated innovative ways to address pollution in fuel sources. “My research explored how to remove toxic sulphur compounds from fuels by exploiting the properties of very small particles of copper, called nanoparticles,” he said.
Byamungu’s work is particularly relevant as countries around the world explore cleaner and more sustainable energy sources. Reducing harmful emissions from fuels remains an important step toward protecting the environment and public health. “We need to explore alternative renewable sources of fuel that reduce the harmful emissions of traditional fossil fuels such as coal or crude oil,” he said.
“My interest in this area was motivated by the rising industrialisation of many African nations,” explained Byamungu. “As more of these nations consume these fuels to accommodate their increasing populations, we need to make sure we learn from the mistakes of the first industrial nations and do better, especially when it comes to environmental pollution.
“I think the research I conducted has potential, tangible industrial applications to make a real difference in the quality of renewable fuels we produce and use, which then has further ramifications on our quality of life as a whole,” he said.
Byamungu’s academic journey is far from over. He plans to continue investigating the potential of copper and other nanoparticles in environmental applications. “Turns out, those small nanoparticles have more and more interesting applications,” he said. “I plan to explore using them, as nanofluids, to remove small plastic particles (microplastics) from water as part of a PhD at UKZN.”
He is particularly excited about the potential impact this research could have on communities across Africa. “I will be applying this process to investigate how it could positively affect the lives of communities in some previously disadvantaged regions of the continent,” he said.
Byamungu thanked those who supported him along the way, particularly his family and the UKZN academic community. “My parents played a big role in shaping the person I am today,” he said. “From a young age, they nurtured my sense of curiosity, which then morphed into a keen interest in research as I was formed at UKZN.”
Outside of academia, Byamungu enjoys working on DIY projects and volunteering in his community. He sometimes assists at his local church, helping to feed unhoused people or serving as an usher.
Looking ahead, he believes empowering young people to experiment, explore ideas and learn from mistakes will be key to Africa’s future.
“The lessons we receive along the way shape who we become,” he added.

author : author email : UKZN Graduate Extracts Big Potential from Indigenous Plants to Claim Top Honours
Summa cum laude master’s graduate, Ms Nolwazi Mcwabe (right), with her mother, Ms Philisiwe Dladla.Ms Nolwazi Mcwabe, who graduated summa cum laude with a Master of Science (MSc) in Engineering (Chemical Engineering), pursued her postgraduate studies with the clear intent of contributing to sustainable development through innovative, locally driven solutions.
Supervised by Professor Amir H. Mohammadi, Mcwabe’s academic journey at the University of KwaZulu-Natal (UKZN) was shaped by a growing passion for green energy and a commitment to unlocking the potential of South Africa’s natural resources.
“I chose UKZN for my MSc because of its strong research focus and excellent academic reputation in my field,” she said. “My undergraduate studies at UKZN sparked my passion for green energy, particularly through the green energy modules I completed.”
Mcwabe’s master’s research, ‘An Experimental Investigation on Bio-wax Extraction from Plant Leaves’, explored bio-wax extraction from indigenous South African plants - an area with significant environmental and economic promise. She focused on extracting bio-wax from locally available plant sources, with the aim of reducing reliance on imported waxes while creating new opportunities for local communities.
“Historically, bio-wax extraction involves removing other compounds like carbohydrates and bioactives before isolating the wax,” she explained. “I tested four local plants (Aloe ferox, Euphorbia tirucalli, Portulacaria afra (spekboom) and Carissa macrocarpa) using multiple solvents to find the best extraction method. One solvent stood out (n-Hexan), but the plants varied in bio-wax yield, giving us a ranking of best to least productive (bio-wax yield rank from highest: Carissa macrocarpa, Euphorbia tirucalli, Portulacaria afra and lastly Aloe ferox).”
The implications of her findings extend beyond the laboratory. “The extracted bio-wax has potential uses as fuel, polish and a sustainable alternative to fossil fuel-based products,” she said. “Using local plants and processes means we can boost South Africa’s economy by reducing import costs, creating local jobs and promoting sustainable agriculture, all the while supporting green energy initiatives.”
Her interest in the field was driven by both environmental and socio-economic considerations. “The potential to create sustainable, local alternatives to fossil fuel-based products motivated me,” she said. “Using indigenous South African plants means we can support local agriculture, reduce our carbon footprint and contribute to green energy initiatives. It’s a win-win for the environment and the economy.”
Her research contributes to sustainable development in South Africa by providing a local, eco-friendly alternative to fossil fuel-based products. “By tapping into the potential of indigenous plants, we can reduce reliance on imported waxes, create jobs and promote green energy, ultimately supporting the country’s economic growth and environmental sustainability,” she argued.
Completing her MSc in just a year was no small feat. Mcwabe credited her success to the support system around her, as well as her own determination. She thanked Mohammadi for his exceptional guidance and support throughout her MSc journey. “His expertise and reputation in the field have been instrumental in shaping my research,” she said.
She also thanked the lab technicians who helped source equipment and chemicals for her experiments, as well as her friends and family. “It wasn’t easy, but they were with me every step of the way. I basically lived at school for a year, putting in long hours to finish my MSc in one year - their encouragement kept me going!”
Now working as a graduate engineer in Mpumalanga, Mcwabe is already building on her academic foundation. “I am continuing to focus on green energy, exploring opportunities to combine it with agricultural waste management,” she said. “I’ve got a chance to do a project with UKZN on sugarcane processing and waste management, which ties in nicely with my interests.”
Her immediate goal is to gain hands-on experience. “I’m keen to gain industrial experience, explore techniques and see how agricultural waste can be turned into usable products,” she said. “Maybe down the line, I’ll pursue a PhD in green energy, but for now, I’m focusing on growing my practical skills.
“I’m grateful for the opportunity to pursue my passion for green energy and sustainability,” said Mcwabe. “I’m excited to apply my skills as a graduate engineer in a company in Mpumalanga and also build on my research project.”
“Who knows, maybe this is just the start of something bigger!”

author : author email : Architecture Master’s Research Seeks Inclusivity for the Visually-Impaired
Ms Erin Naidoo’s research on more inclusive architectural design earned her a master’s degree.Ms Erin Naidoo’s master’s research challenged the ocular-centric, or vision-biased, design of built environments not only to consider the experiences of visually impaired users, but also to expand sighted users’ immersive, fully sensory experiences of public architecture.
Having been fascinated from an early age with design and meaningful building creation, Naidoo spent time watching people and observing how they use and respond to their surroundings and how these are intentionally shaped for different purposes, such as the refuge of a school compared to the vibrancy of a shopping mall.
Coming from Queensburgh, enrolling at the University of KwaZulu-Natal (UKZN) for her undergraduate studies was a given, thanks to its strong architecture programme and the proximity to her home, which eased the transition from school to university. Naidoo went on to complete her honours degree at the University before embarking on a master’s course. She said the Architecture studio and LAN on campus became like a second home and enabled her to bond with peers through long studio hours and shared experiences, a deeply rewarding aspect of her studies.
Naidoo found success in her work, receiving the Garth Moyes Good Fellowship Award in her first year (voted on by her peers), and the Nsika Foundation Scholarship, which supported her studies through to master’s level.
Naidoo’s passion for architecture is undergirded by her perspective of the discipline as a fusion of people and place.
“Beyond just creating beautiful structures, I am driven by the architect’s unique ability to impact both the environment and the daily experiences of people’s lives positively,” she said.
Her research tackled the emphasis of sight and visual aesthetics in architecture, which can be disorienting for visually impaired users; she investigated how architecture can evolve to embrace design strategies such as touch, sound and scent to create inclusive environments where everyone, regardless of visual ability, can experience and appreciate architecture beyond what is seen. Her study was titled: ‘Exploring Visually-Impaired User Experiences of Public Architecture Towards a Multi-Sensory Community Library in Berea, Durban’.
This approach reframes disability from a ‘tragedy’ into an opportunity for architectural innovation.
“In South Africa, visual impairment is a prevalent disability, yet our public buildings often only meet minimum technical ‘access’ standards and compliance rather than providing a meaningful, enjoyable experience,” said Naidoo.
She sought to advocate for a shift toward Universal Design, in which designing for and considering the most vulnerable results in richer, more legible and more considered environments for everyone. This also promotes social cohesion using public architecture as a tool to challenge and reshape societal perceptions of impairment.
Naidoo was struck by the independence of the visually impaired community, whose mindset, she says, focuses on an alternative way of belonging rather than on disadvantage, and this led Naidoo to question whether it is the sighted who are ‘impaired’ by an over-dependence on vision. She found herself learning from this community in a humbling moment that taught her not to view people with impairments as ‘subjects’ but to treat them as expert consultants on the human experience.
The design component of her research was awarded third place at the Corobrik Regional Student Awards.
Despite beginning her master’s with less industry experience than her classmates, she overcame this ‘imposter syndrome’ by following a rigorous schedule of dedication and by surrounding herself with a strong support group, which fuelled her hard work.
“Stepping out of my comfort zone ultimately allowed me to find my voice and taught me that while architecture demands individual grit, you never truly reach the finish line alone,” said Naidoo.
While conducting research, she worked as a tutor and mentor for undergraduate Architecture students, demonstrating strong time management and discipline to balance her workload and strengthen her own learning while assisting others.
Naidoo is now applying her knowledge and skills in a professional setting and once completing her candidacy, she hopes to travel and possibly work abroad, gaining exposure to architecture on a global scale. In the future, she aspires to return to academia and pursue a PhD in architecture.
Naidoo thanked her supervisor, Dr Bridget Horner, for her guidance, and her parents and siblings for their constant support and reassurance. She acknowledged her friend and classmate, Mr Jishen Dhurgabarsad, for his reliability and for sharing her journey, and the Nsika Foundation for its generosity in supporting her studies.

author : author email : Computer Engineer Raises ‘Winner’s Flag’ and Earns a PhD
PhD in Computer Engineering graduate Dr Mortda Adam with his daughter Ms Aseel Adam, wife Ms Zobiada Adam, and son, Mr Ahmed Adam.Graduating with a Doctor of Philosophy in Computer Engineering from the University of KwaZulu-Natal (UKZN) is far more than a ceremonial celebration, says Dr Mortda Adam, it is the culmination of years of perseverance, sacrifice and unwavering determination.
“Graduating is the moment to look around and realise a major milestone is complete,” Adam reflects. “It represents a deep, heavy experience in my field where I have made a genuine contribution to the community.”
That sense of accomplishment is hard-earned. He recalls the many difficult mornings when exhaustion weighed heavily, yet he pressed forward, driven by a clear goal. “Even though the path was hard, challenging and costly, I chose to keep going… and raise the winner’s flag.”
Originally from Sudan, Adam began his academic journey with a Bachelor of Science in Computer Science from Omdurman Islamic University, followed by a master’s degree at Sudan University of Science and Technology. His early career as a lecturer proved transformative. Teaching computer technologies gave him a broad and insightful perspective on the rapidly evolving tech landscape, sparking a desire to pursue deeper, specialised research.
This passion ultimately led him to UKZN, an institution he chose for its strong academic reputation and global research contributions. There, Adam immersed himself in cutting-edge fields such as computer vision, deep learning and real-time object detection; areas that would shape both his doctoral research and his long-term vision.
At the heart of Adam’s PhD, titled: ‘Deep Learning Approach for Object Detection on the Road for Edge Devices’, is a practical challenge with global implications: how to help computers ‘see’ and understand road environments more effectively. His research focuses on improving artificial intelligence systems that detect objects such as vehicles and pedestrians in real time; technology that underpins autonomous driving and advanced traffic monitoring systems.
“I worked on making these systems both accurate and fast, but also lightweight enough to run on devices with limited computing power,” he said. Many existing models are powerful but too slow or resource-heavy for real-world use, particularly in environments with constrained infrastructure. To address this, Adam enhanced a well-known detection model, introducing innovative, efficient techniques, including a newly developed attention mechanism, to improve performance without increasing computational cost.
The result is a significant step forward: smarter, faster and more efficient object detection systems that can operate effectively even on low-cost hardware. This has far-reaching implications, particularly for developing regions.
Adam’s motivation is deeply rooted in real-world concerns. Witnessing the widespread challenges of traffic congestion and road accidents inspired him to pursue research that could make a tangible difference. “These issues have serious consequences such as loss of lives, wasted time, economic costs and environmental pollution,” he said. “I wanted to contribute to solutions that improve road safety and transportation efficiency.”
His work does exactly that. By enabling more accessible and efficient intelligent systems, his research supports advancements in driver assistance technologies, autonomous vehicles and smart city infrastructure. In practical terms, this could mean earlier detection of hazards, improved traffic flow and better decision-making systems, ultimately helping to save lives and reduce environmental impact.
Currently working as a lecturer, researcher and software engineer, Adam continues to bridge the gap between academic theory and real-world application. His future aspirations are firmly focused on developing scalable, cost-effective technologies that can be widely adopted, particularly in resource-constrained environments.
“I want to design systems that are not only innovative but also affordable and deployable,” he said. “The goal is to support safer, smarter and more sustainable cities in Africa and globally.”
Adam credited his supervisors and mentors for their guidance and thanked his parents, whose values shaped his path. He also highlighted the unwavering encouragement of his wife, children, friends and colleagues.
Beyond academia, Adam finds balance in simple but meaningful pursuits. Long walks and swimming provide him with clarity and help maintain a healthy equilibrium between his professional and personal life.
Grounding his journey is a philosophy that continues to guide him forward: Focus on what must be done, regardless of circumstances or comparison to others. “I always ask what I can do better to reach my goals because I believe that what the mind believes, it can achieve.”

Dr Silindile Gumede (centre) with her sister, Ms Nana Gumede (left), and her mother, Ms Simangele Khanyile.Dr Silindile Gumede, who was awarded a PhD in Engineering (Chemical Engineering) from the University of KwaZulu-Natal (UKZN), selected the Institution as her doctoral home because of its excellent reputation in education and research.
Gumede’s journey, however, has not been without difficulty.
When she first arrived at UKZN as an undergraduate Engineering student, Gumede - from the rural area of Mtubatuba where there was no electricity or water at that time - struggled to adjust both academically and socially.
Students from such backgrounds often face gaps in prior preparation, limited resources, and unfamiliar systems, she explained. These challenges led to her academic exclusion.
“At the time, it felt like the end of my journey in Chemical Engineering,” she said. Unwilling to wait a year to return, she enrolled at the Durban University of Technology (DUT), keeping the full truth from her family. “Coming from being a top student in my district, I was ashamed and felt like I had disappointed them,” she reflected.
At DUT, Gumede rebuilt her confidence and excelled, completing both her undergraduate and Master of Engineering degrees with distinction.
“Returning to UKZN for my PhD was more than just an academic goal; it was a full-circle moment of growth and perseverance,” she said.
Her personal journey has shaped her current approach as a lecturer at DUT, instilling compassion and understanding for students navigating their own challenges.
Gumede’s doctoral research, titled: ‘Recovery of Valuable Metals from Spent FCC [Fluid Catalytic Cracking] Catalysts Using Leaching Extraction Technique’, focused on recovering valuable metals from waste materials, specifically spent refinery catalysts. These catalysts are used in refineries to accelerate chemical reactions that convert crude oil into useful products like petrol and diesel. Over time, they lose their effectiveness and are discarded as waste; however, these materials contain valuable metals such as vanadium and nickel, which are in high demand globally.
Using a process called leaching extraction, Gumede developed ways to safely extract vanadium and nickel from this waste. “In simple terms, I’m turning industrial waste into valuable resources,” she explained. “This not only reduces environmental pollution, but also helps conserve natural resources and contributes to advancing cleaner and more sustainable energy solutions.”
Her interest in this field was rooted in her earlier work during her Master of Engineering research, where she focused on wastewater treatment and the removal of heavy metals from acid mine drainage. That experience sparked a passion for practical environmental solutions. When she approached her PhD supervisor, Professor Amir H Mohammadi, and her co-supervisor, Dr Mbuyu Ntunka, she shared her background and interests, and together they identified this research area as a natural fit. “It strongly resonated with me because it contributes to sustainable resource recovery,” she said.
The significance of Gumede’s research lies in its dual contribution to environmental protection and economic development. The extraction of metals from spent catalysts represents a strategic approach to meeting a portion of the demand for these valuable materials, which are essential for technologies such as renewable energy systems and electronics, while the process contributes to reducing environmental impact upon disposal by applying the principles of a circular economy, where waste is reused, and helps address global challenges related to resource scarcity and sustainability.
Looking ahead, Gumede plans to continue her career in academia as both a researcher and lecturer. She hopes to expand her work into scalable industrial applications and to collaborate with industry to implement sustainable technologies.
Central to her success was the unwavering support of her mother, who, despite having no educational background, prioritised education and made significant sacrifices. “Her belief in me laid the foundation for everything I have achieved, and she remains my greatest source of inspiration,” Gumede said, adding that her mother never misses an opportunity to celebrate her achievements.
As a mother herself of two sons, Gumede had to balance the demands of a PhD with mothering duties and maintained her physical and mental well-being through gym sessions and running. “Those moments gave me space to reset, stay focused and keep going despite the challenges,” she said.
“I would like my story to serve as a reminder that setbacks are not the end of the journey,” said Gumede. “You will encounter the most difficult moments of your life, but they may become a turning point and teach you resilience.”

The demanding nature of engineering studies fostered a sense of camaraderie among students, forged through long hours of study, collaboration and perseverance. “The shared challenges created a bond that extends beyond graduation,” he said, acknowledging the resilience and determination of those who undertook the journey alongside him.
Naicker remains committed to continued professional and academic development. He intends to pursue a master’s degree once he has identified a suitable area of specialisation, while simultaneously working toward registration as a Professional Engineer (Pr. Eng). His long-term goals include contributing meaningfully to the engineering sector while maintaining a balanced and sustainable lifestyle.
Naicker attributes much of his success to the steadfast support of his family. He thanked his parents, Mr Adrian Naicker and Mrs Reanna Naicker, for instilling the values and discipline that have guided his journey. He also recognised his sister, Thashnee, as a source of inspiration, and acknowledges the encouragement of his fiancée, fellow UKZN graduate Ms Natasha Seethumbaram Gounden as well as the support of his friends and peers.
Beyond his professional commitments, Naicker maintains an active and balanced lifestyle. His interests include spending time with family and friends, participating in religious activities, maintaining physical fitness through gym training, jogging, swimming, reading and gaming.
Central to his outlook is a guiding principle taken from the Bhagavad-Gita: “For him who has conquered the mind, the mind is the best of friends; but for one who has failed to do so, his very mind will be his greatest enemy.” This philosophy underscores the discipline and focus that have defined his academic success.
